## What modifications were made to 10.4Fx?
10.4Fx contains modified widget code to work with OS X Tiger and the 10.4 SDK, modified font code to use Apple Type Services instead of CoreText, disables OpenGL graphics acceleration and WebGL (which are incompatible with tiger), adds its own MP3 audio decoder, and includes AltiVec- and PowerPC-specific code for JavaScript acceleration and decoding of WebM, JPEG and HTML. Here is a more or less complete [[list of changes in TenFourFox|TechNotes]].

## Does Mozilla support TenFourFox?
**No. TenFourFox is not an official Mozilla build or product.** That said, our project lead is a member of the Mozilla security group, and all our contributors routinely upstream patches we believe of benefit to other PowerPC builds of Firefox, which Mozilla accepts. However, we maintain separate support networks, build systems, and distribution infrastructure which Mozilla has no role in operating; no one working on this port is a Mozilla employee; and the project receives no material support from Mozilla. In short, we are no different to Mozilla than any other 3rd-party "[Tier 3](https://developer.mozilla.org/en-US/docs/Supported_build_configurations)" port.
## What is the difference between the _stable_ and _unstable_ branches?
## Why do you put that funny "FPR" before your version numbers?
Starting with Firefox 10, Mozilla introduced the Extended Support Release, or **ESR**. The ESR maintains a consistent version for approximately one year, receiving bugfixes and security updates from Mozilla, but no new Firefox-general features. Roughly every seventh version is an ESR (so 10, 17, 24, 31, 38, and so forth). This is the basis of the _stable_ branch.
Until TenFourFox 45, TenFourFox versions kept pace with Firefox, and corresponded generally with the feature set of the same version of Firefox. Stable releases were based on the current Firefox Extended Support Release (ESR) and unstable releases were based on the released mainstream version of Firefox. We called this state "source parity:" we built from a modified version of Firefox's current source code and kept pace with their changes.
The stable branch, despite its name, does receive selected new TenFourFox features and does have "betas" for testing them, but does not receive other feature updates from Mozilla. Although it is not as technologically advanced as the unstable branch, it is based on tested and stable code and receives security updates, and therefore **the stable branch is the recommended version for most users.**
Unfortunately, between Firefox 45ESR and 52ESR, Mozilla made several important low-level changes that would have caused substantial problems with older versions of OS X. Additionally, after Firefox 54 Firefox now requires the Rust compiler to build the browser, which has never been supported on PowerPC OS X and has several low-level technical requirements which are not possible prior to OS X Lion. It would have been very difficult to build versions from Firefox 46 to 53, and is now impossible to build versions from Firefox 54 on.
The _unstable_ branch of TenFourFox includes new Firefox-general and TenFourFox-specific features for testing. Note that not every version of Firefox has a corresponding version of TenFourFox; we sometimes skip versions for technical or timing reasons. In addition, because the unstable branch is not release-quality, it frequently has known bugs and therefore is only recommended for developers and advanced users. Nevertheless, we encourage technically proficient users to help us develop and keep the port viable. If you are interested in helping to test the unstable branch, please visit the [TenFourFox Development](http://tenfourfox.blogspot.com) blog.
As a result, we parted ways from Firefox's source code with the ESR version of 45.9 and started backporting important features from later versions of Firefox to this reliable platform base. We call this state "feature parity" to demonstrate that we don't use Mozilla's current source code in its entirety, but we do try to support as many of the current features as feasible. These releases are tagged as "FPR" or "Feature Parity Releases" so that they are not confused with later versions of Firefox by users or websites checking the user agent.
Each FPR includes security and bug fixes as well as varying numbers of new features ported sometimes from the very latest version of Firefox. While the FPR series do not implement every single feature due to feasibility or missing system requirements, they are designed to keep the browser as relevant and compatible with most current websites as possible.
## Are there other PowerPC OS X builds of Firefox?
We are no longer aware of other current builders. For a period of time AuroraFox issued a 10.5-only build, but is no longer supported as of Firefox 20. There are also some older Firefox rebuilds for Power Macs made directly from Mozilla's source code, but none of them are still maintained either. The long-running SeaMonkeyPPC (10.5 only) has also ceased updates, as has the OS X/ppc version of the Tor Browser Bundle (compatible with 10.4/10.5 and based on 10.4Fx code).
However, for Thunderbird users, there is [Tenfourbird](https://en.osdn.jp/projects/tenfourbird/) which is also based on 10.4Fx code and compatible with 10.4 and 10.5.
For Thunderbird users, there was [Tenfourbird](https://en.osdn.jp/projects/tenfourbird/) which is also based on 10.4Fx code and compatible with 10.4 and 10.5. Tenfourbird has not been updated since 38.9.
We do not officially endorse any alternative build (other than our own, of course), although some of these builders have contributed to this project.

Please give us the benefit of the doubt here: we _do_ dogfood our own browser. In fact, the FAQ you're reading was written on a G5 using TenFourFox. Serious crippling issues like this are usually due to something local; failure to do basic browsing tasks, let alone even start up, would be rapidly apparent to our testing audience. To diagnose the problem will need a little detective work.
* First, verify you are running the correct processor build. The G5 build will crash on a system that does not have a G5 processor; the G4 build will crash on a G3 processor.
* Next, try to start in safe mode -- hold down the Option key as you start 10.4Fx. This will disable any problematic extensions and themes and certain other browser features. If this fixes the problem, you should attempt to find which add-on or feature is the problem. Some older add-ons may cause serious issues with the browser.

## Can 10.4Fx run on an Intel Mac with 10.4, 10.5 or 10.6?
Yes, but: **Intel Macintoshes are not supported. Please do not ask for support on Tenderapp.** Because Intel is a better-known architecture to attackers than PowerPC, both Intel 10.4 and 10.5 are much more likely to be successfully attacked than PowerPC, even though both technically have the same or similar security holes. **You are strongly advised to update to at least Snow Leopard (10.6) and run Firefox ESR 45**, which will give you a more current operating system and still lets you run most OS X PowerPC applications. [Apple still sells Snow Leopard](http://www.apple.com/shop/product/MC573Z/A/mac-os-x-106-snow-leopard), which even the earliest Intel Macs can run and is a necessary prerequisite for later versions of OS X. Firefox ESR 45 still runs on Snow Leopard, Lion and Mountain Lion (10.6-10.8), and will be supported until June 2017.

That having been said, if you are absolutely unable or unwilling to upgrade your Intel Mac, it is possible to run TenFourFox on it under the Rosetta PowerPC translator that comes with 10.4-10.6. However, because TenFourFox uses advanced custom code specific to the PowerPC architecture, Rosetta may have compatibility problems running the browser. Follow the steps below:
* First, make sure you are using the G3 version; the others, particularly the G5 version, will not work with Rosetta under _any_ circumstances.
* Second, if the browser crashes when you try to start it (just double-click it like any other app), try to restart it in safe mode (hold down the Option key as you start the browser). If this allows the browser to start, you will need to disable the JavaScript compiler permanently. Go to `about:config` by typing it in your address bar. Find all the preferences starting with `javascript.options.baselinejit` and `javascript.options.ion` and make sure they are set to `false` by double-clicking the value. If they are already `false`, leave them alone. **Do not change any other options.** Restart 10.4Fx and see if this fixes the problem. You can also try this if you experience inexplicable crashes with 10.4Fx on your Intel Mac, even if it appears to start normally.
* First, make sure you have upgraded to Snow Leopard if at all possible, which will still run PowerPC software, and has many bug and security fixes. [Apple still sells Snow Leopard on CD](https://www.apple.com/shop/product/MC573Z/A/mac-os-x-106-snow-leopard), and all Intel Macs available prior to 10.7 are compatible, including 32-bit systems.

In general, using Rosetta to run TenFourFox will be noticeably slower on an Intel Mac, even if you are successful in starting it up. The reason is that Rosetta must convert all the PowerPC code in it into Intel machine language on the fly and there is no AltiVec or other acceleration support. As a result, it will appear to be much slower than Firefox 3.6, 10 or 16, all of which have native Intel code. However, it is more up-to-date with security patches and fixes, so you may prefer it if your Intel Mac is sufficiently fast enough.

At one time a TenFourFox 17.0.2 was available for Intel, donated by a contributor, but is no longer being maintained. You should not use this version anymore due to known security vulnerabilities. If you can help with building and maintaining a newer release, please post to the development blog.
Finally, let us say it again: **Intel Macintoshes are not supported under any circumstances, period.** Power Macs remain the primary focus of support and development; any indulgence of Intel Macs is on a best-effort basis only. Seriously, please do us all a favour and install Snow Leopard and run the real Firefox ESR.

You will get automatic prompts to update if the browser detects your version is not in sync with the version available. Sometimes this may occur even if you appear to be using the same version (we do not bump the version number between official releases to avoid getting out of sync with Mozilla, but the browser has a different build ID). If you are ever in doubt about the version you have, the [TenFourFox Start Page](http://www.tenfourfox.com/start) will tell you if you are using the most current release.
## Web pages keep saying they don't support TenFourFox any more.
## Web pages say my browser is too old.
TenFourFox is detected by many sites as Firefox 45, which technically has not been supported by Mozilla since 2017. This is on purpose to prevent sites from incorrectly enabling features that TenFourFox may not support, but some sites that would otherwise work perfectly fine with TenFourFox will then complain the browser is too old.
For these sites that mistakenly use the browser's "user agent string" to determine its feature set, you can change it from within TenFourFox by going to Preferences and selecting the TenFourFox tab. From the User Agent dropdown, select an alternative. Select the earliest browser version that is compatible with the site you need; selecting an overly current version may cause the site to enable features TenFourFox might not ever support. Reload the page to see if the change fixed the issue. You may need to experiment with this setting to get some recalcitrant sites to "stick."
The current user agent setting is applied to all sites you visit, but you can change it at any time. **If a site doesn't seem to be working properly, make sure your user agent is set to the default before you report a bug.**

## 10.4Fx does not display some fonts (Tamil, Arabic, ...) correctly.
10.4Fx does not support CoreText, which is needed to use the typographic information in certain AAT-encoded fonts that come with later versions of Mac OS X. Without this information, certain ligatures and glyph reordering rules cannot be utilized, and the font will appear but not quite correctly. The font renderer in 10.4Fx does support Arabic and other international scripts, but requires OpenType or Graphite fonts for the special language-specific features; see [[our tech notes|TechNotes]]. Fortunately, many websites now provide these fonts as downloadable webfonts and TenFourFox can generally use them, so this problem is less common than it used to be.
## 10.4Fx sometimes pops up a window saying "bad font detected."
## 10.4Fx sometimes shows weird little boxes instead of letters or symbols.
Font rendering in TenFourFox is accomplished with an older library called ATSUI instead of the CoreText library used in current versions of Mac OS X. CoreText is not fully implemented in 10.4 and has stability issues in 10.5, so we use ATSUI instead, which supports nearly all the same features. Unfortunately, due to bugs in ATSUI which Apple never corrected, some downloadable webfonts are incompatible and display characters as weird little "boxes" (with a character resembling an "A," or sometimes a series of tiny hexadecimal digits). On 10.4 systems, an error window may also appear; on 10.5, the browser may even crash under certain circumstances.
We cannot automatically detect these fonts due to limitations in the system libraries we require to remain compatible with 10.4, so we keep a "blacklist" of webfonts and webfont URLs that are known to cause problems. When the browser is requested to use a font on the blacklist, it quietly drops it and switches to a fallback font which will hopefully display correctly.
Unfortunately, maintaining the "blacklist" is a manual process. Periodically as URLs change or new fonts are used, the blacklist must be updated. If a site you use is causing this problem, you can submit font URLs for investigation. While you can just open a ticket on Tenderapp with the offending website and wait for us to figure it out, a better way to get the problem fixed is to [follow the steps in this support ticket](https://tenfourfox.tenderapp.com/discussions/problems/8558-turbotax), which will greatly expedite the process of getting the problem fixed.

If you get this window frequently, there are a few ways you can improve the browser's script performance. Try some or all:
* Remove unnecessary browser add-ons. These sometimes will interfere with some sites.
* Consider enabling basic adblock (next question), which can improve browser performance overall.
* Use the NoScript add-on and allow JavaScript only to run on certain necessary sites.
* [Disable the unresponsive script warning entirely.](http://tenfourfox.tenderapp.com/discussions/problems/174-unresponsive-script-warning)
## How do I use the built-in adblocker?
TenFourFox adds support for *basic adblock*, which blocks certain nuisance scripts that implement ads, trackers, cryptominers and other kinds of browser-based malware. As a nice side effect, this interferes with many ads and adblocker-blockers and improves the overall performance of the browser by reducing the amount of JavaScript that must be executed.
Basic adblock is just that: basic. It does not, nor is it designed to, completely block all advertising content and some sites can still track you with non-JavaScript means such as cookies and beacon images. If the script is part of the basic functionality of the website, even if it also serves ads or does user tracking, by policy we don't block those.
You can use basic adblock in combination with other adblock add-ons, though basic adblock can be substantially faster if used by itself. Basic adblock also functions in Private Browsing windows, which implement additional tracker blocking.
To enable basic adblock, go to Preferences, click TenFourFox, and check "Enable basic adblock." You can [suggest other sites](https://tenfourfox.tenderapp.com/) to block on Tenderapp.
## Does 10.4Fx support Firefox add-ons?

Yes, if they are compatible with Firefox 45 and do not require an Intel Macintosh. While many current versions of add-ons require later versions of Firefox, older versions will generally function, and you can still find these older versions from [Mozilla Add-ons](https://addons.mozilla.org/). We offer [an archive of these add-ons](https://sourceforge.net/projects/tenfourfox/files/addons/archive/), though we do not support them.
Remember: add-ons and plugins are not the same. **Add-ons are supported in 10.4Fx. Plugins aren't.** [[Here's why we don't support plugins|PluginsNoLongerSupported]].
Note that adding large numbers of add-ons will make your browser *slower*, and a badly-coded add-on may cause your browser to act in unexpected ways. If the browser starts acting incorrectly, consider temporarily disabling or removing add-ons to isolate the problem. You can view the addons that are installed and disable or uninstall them as necessary by going to Tools, Add-ons.
Remember: add-ons and plugins are not the same; [[we don't support plugins and here's why|PluginsNoLongerSupported]]. That said, even though we permit add-ons, **add-on support is best effort only**.

## Does 10.4Fx support `asm.js`?
Yes, but without special acceleration; the regular JavaScript JIT is used instead. Additionally, some scripts assume the computer is little-endian (all Power Macs are big-endian). While there is code in TenFourFox to compensate for this under limited circumstances, some scripts will still not run or will malfunction. Fixing this problem would (in some cases severely) impact the performance of other types of JavaScript, so this is not likely to change.

## Why do you make me test my bug reports against the current Firefox? I can't run it on my Mac!
In the years after Firefox 3.6, Mozilla introduced many large layout and interface changes. Fixing Mozilla bugs is out of our purview and most of this app is still Mozilla's code. To keep us focused on our mission of keeping Firefox compatible with the Power Mac, we need you to make sure your bug does not also occur in regular Firefox. If it does, it's not our bug.
We realize that the whole point of TenFourFox is to run Firefox on systems that Mozilla no longer supports, so comparisons to any Tier 1 platform are accepted, including Windows, Linux and Mac OS X 10.6+. However, unless your bug report is clearly specific to 10.4Fx, **if your bug report does not compare behaviour with stock Firefox, it will be marked invalid. _Firefox 3.6 doesn't count!_** We don't mean to be jerks, but we need to keep our heads above water and not spin our wheels -- or there won't be a TenFourFox in the future.
