Why can't I upgrade to the most recent Firefox with a Mac 10.5.8

more options

I'm trying to update Firefox 3.0.10. I have a Mac 10.5.8 with 512 MB of SDRam. When I try to upgrade to the most recent Firefox it tells me my computer isn't compatible, but also tells me that Osx 10.5 with 512 MB of ram should work. Any suggestions? Is there a previous Firefox update which could work, and how would I go about finding that previous update.

Thanks, sorry I'm not so good at this stuff.

Firefox 3.6.x is the last available from Mozilla for PPC Macs.

Download Firefox 3.6.26 and install it - https://support.mozilla.com/en-US/kb/Installing+Firefox+on+Mac


For older Macs that aren't supported in the Firefox 4+ versions, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .
