My system is Mac 10.4.11. I want to upgrade to firefox 4.1 but the icon had a block sign (∅) over it when I went to drag it to the application. Since I could find no compatibility link, I am not sure I can upgrade using my current system. What does the block out sign mean and where can I see compatibility recommendations for my system?

Firefox 4 doesn't run on a PowerPC Mac.

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:
