I love using Firefox, it's by far my favorite browser. But when I opened it this morning, it says I am no longer protected because of the older version I'm using. I want to download the new version but it says that it is incompatible with my computer.  ?? This is the same operating system I've used and it's on the list of compatible OS....mac 10.5.

HELP please! I miss it already!

Firefox 4 requires at least OS X 10.5 and an Intel Mac.

For an unofficial Firefox 4 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:

Thank you! I'll go with TenFourFox and hope Firefox comes to its senses.
