Be careful to pick the right version for your processor and be aware that also Firefox can mess up an old profile (it happened to me in the past!), especially with some extensions) )ĭon't believe the absurd bad reviews below! :-D I've tested all recent versions on an iMac G5 2.1 GHz and a Mac Mini G4 1.25 GHz. I've also applied the fonts advice on my Intel Macs with Waterfox and Firefox. Now, with its RAM maxed out, TFF's built-in basic adblock alone is the overall best choice - if you don't mind trackers, etc.īefore applying those advices, TFF ate CPU for 50s at launch before calming down, then nearly the same time for loading very heavy sites: now I've achieved 20s launch time and even the heaviest site takes less than 20s to display ('normal' pages load between 4s and 8s). My little G4 mini was lacking RAM until today, so it was faster filtering heavy pages with uBlock +uMatrix +Decentraleyes (as calculations were made in virtual memory i.e. final point: built-in basic adblock of TFF.my second point is about extensions: most of you already know it, but keep them as few as possible.Thanks to TFF's dev, I've learned that those browsers enumerate the available fonts in your system, so minimizing their number will gain a considerable amount of time, especially for slow machines.My FPR15 review will be more of a 'best practices with TFF and any Firefox based browser':

For these and other reasons, TenFourFox does not run plugins, and they cannot be enabled. Most importantly, Adobe Flash for PowerPC is no longer maintained and has known security risks that can crash or leak data, some sites require versions not available on the PowerPC, and QuickTime for Leopard will lose its own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. 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. Sites will now act as if no plugins were installed at all. TenFourFox no longer supports plugins or Flash - As of the previous TenFourFox 6.0, for the following reasons plugin support ships disabled. On the G4 Mac open the Terminal app (in Applications -> Utilities) and type the command machine. 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.

It comes in different tuned versions for specific PowerPC processor families: 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.
