I cannot upgrade to FFv4.0, even though I am using OSX 10.5.8, I have 2.25GB RAM and 6.24GB disk space. I can't even give feedback via FF3.6...this is crap!
I cannot upgrade to FFv4.o.
According to Mozilla website software specs (http://www.mozilla.org/en-US/firefox/4.0/system-requirements/), I have to be running either OSX 10.5 0r 10.6 - I am using 10.5.8. So I assume I have the minimum requirement?
Under recommended hardware (not required or minimum) it says I also need 512MB of RAM (I have 2.25GB), and 200MB of disk space (I have 6.24GB).
I can't even give feedback via FF3.6, which is ridiculous.
What am I doing wrong?

latest version of Firefox 8 download it from
Firefox 4 versions and later do not run on a PowerPC Mac.
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.
For an unofficial Firefox 8 compatible version (TenFourFox) that runs on PowerPC Macs with OS X 10.4.11 or OS X 10.5.8 you can look at:
Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
