TenFourFox system requirements
TenFourFox requires a G3 Power Macintosh, Mac OS X v10.4.11 or Mac OS X v10.5.8, 100MB of free disk space and 256MB of RAM. Video playback will be poor on systems slower than 1.25GHz; we recommend a G5. Intel Macintoshes are not supported (and will be mercilessly mocked)
I love that last line :~)
Time to download it and give it a spin!
A 6 year old G5 iMac is still worth more on ebay than a brand new acer sitting on the local walmart shelf (and runs better also)!!
Long live PPC!!
