TenFourFox

TenFourFox is a fast, efficient Web browser always based on the current version of Firefox, but unlike the main distribution TenFourFox is compatible with OS X 10.4 and 10.5 running on PowerPC processors. It comes in different tuned versions for specific PowerPC processor families:

• TenFourFox G5
• TenFourFox G5
• TenFourFox G5
• TenFourFox G4 - build 7450
• TenFourFox G4 - build 7400 (also for 7410)
• TenFourFox G3
• TenFourFox G3

If you feel unsure what type of PowerPC processor your Mac has, go to the Apple menu and choose "About this Mac" and check the processor field. On the G4 Mac open the Terminal app (in Applications -> Utilities) and type the command machine.

TenFourFox no longer supports plugins or Flash - As of the previous TenFourFox 6.0, for the following reasons plugin support ships disabled. Sites will now act as if no plugins were installed at all. Plugins on PowerPC are of special concern because Mozilla is making updates to their plugin architecture which may require the plugins themselves to be updated, and there are certain difficult-to-correct bugs with them already on Tiger. Most importantly, Adobe Flash for PowerPC is no longer maintained and has known security risks that can crash or leak data, some sites require versions not available on the PowerPC, and QuickTime for Leopard will lose its own support with the release of OS X Lion. For these and other reasons, TenFourFox does not run plugins, and they cannot be enabled.

New:

• Additional JavaScript ES6 and ES7 features and performance improvements

Fixed:

• All relevant security and stability fixes from Firefox ESR 60.4.0.
• data: URIs are now opaque-origin, reducing XSS risk. A shim is in place to maintain add-on compatibility.
• For performance, CSS error reporting is now disabled by default in release builds. Advanced users can reenable it by setting layout.css.report_errors to true from about:config.
• The workaround for sites using Cloudflare Rocket Loader is more complete.
