I have an old MacBook laptop and it doesn't have enough memory for a new version of Firefox; why can't I keep the old version which works fine on this computer?

I am running Firefox version 3.6.23 and I keep getting a message saying that I should upgrade, but I am working on an older MacBook laptop computer with 640 MB of memory and an 800 MHz Power PC G4 with Mac OS X version 10.4.11 and when I tried to upgrade, your message said that it couldn't happen. Please let me keep running the older version of Firefox because it works fine on my old laptop.

The latest 9.0.x version is not compatible with your os.

see :Firefox 9 System Requirements

Firefox 4 versions and later do not run on a PowerPC Mac(like yours) and require at least OS X 10.5 and an Intel Mac.

The latest supported version for your os is 3.6.25 (you have 3.6.23), your can download from here:

http://www.mozilla.org/en-US/firefox/all-older.html

see : Firefox 3.6 System Requirements


[For older Macs that aren't supported in Firefox 4+ versions, if you like, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8]
