..browser update for PPC..
For those who still wish to use their older pre-Intel Mac online, there is
a more recent TenFourFox version browser (if you're not using it already)
that could allow most adequate online experience based on FPR Firefox.
Release information 'feature parity release' tenfourfox:

And then there's a site-specific browser tool for TenFourFox that may
help ration your system resources by limiting one window one site in
your old vintage Mac. I've used a "FoxBox" for gmail and other sites
where the desired focus is for one topic or one site. And less controls.

Given I've several pre-intel Apple Macintosh whose hardware has limits
online, the TenFourFox browser has provided fairly good experience;
most sites load and work properly, this supports HTML5 but not Flash.
{Also for those who wish to migrate bookmarks from older pre-intel
Mac firefox browser; once you've moved them into TenFourFox the
tool provided by Mozilla allows Firefox Sync of bookmarks. It works.}
Just thought to add something current to these old hardware threads
that can be useful across most build models of pre-Intel Mac computer.
In any event...
Good luck & happy computing! 🙂
