This often happens immediately after Firefox has been installed or updated from a previous version. Some firewall software may silently block Firefox from running.Please read this before reporting any new bugs. This list covers some of the known problems with Firefox 2. I have no problem adding bookmarks in FF3. I'm messing around with the bookmarks on FF3 and I had a couple of questions. The Organize Bookmarks window changed a bit since 2.0.0.14. Firefox For Mac Os X 10.5 Leopard (powerpc) I've got this issue since Beta5 or RC I think.For older Macs that aren't supported in Firefox 4 thru 8, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8. You have the latest version of Firefox for PPC Macs and for 10.4.11, the Firefox 4+ versions require Intel and 10.5.8 or higher.While insecure versions of Firefox will continue to work on OS X 10.8 and earlier, using an up-to-date version of Firefox on a supported version of Mac OS will provide you with the best and safest.

Note: If you have Mac OS X 10.7 (Lion) or 10.6 (Snow Leopard), you will need to download OS X El Capitan before you can upgrade to the latest Mac OS. However, we strongly recommend you upgrade to at least OS X 10.6 Snow Leopard or higher as Firefox 16 is no longer updated by Mozilla and therefore not secure anymore. If you’re using OS X 10.5.8 Leopard then you can still download Firefox 16 for Macs which works on 10.5.8.
