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:. 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Most importantly, Adobe Flash for PowerPC is no longer maintained and has known security risks that can crash or leak data, some sites require versions not available on the PowerPC, and QuickTime for Leopard will lose its own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.
Version 45.19.0: New:. Additional DOM (issue 519, issue 520) and JavaScript ES6 (issue 392) features. Support for noopener windows (issue 522), improving site security Fixed:. Mac tutorials for beginners. All relevant security and stability fixes from Firefox ESR 60.3.0 (issue 526). MSE is now enabled by default (issue 524), fixing a playback issue with YouTube.
It can still be disabled from the TenFourFox preference pane. Note that some sites may no longer function with MSE disabled, and VP9 playback may be lower performance on some systems. Additional entries added to the built-in basic adblock.
