I downloaded firefox 3 and followed thier online instructions. Now it is on my taskbar and when I click on it... it bounces .... then NOTHING! No web browser pops up wth!!! Any help would be greatly appreciated.
We need some more specifics. Which version of OS X (10.3.x, 10.4.x, etc.)? What is the speed of your iBook?
There have been many revisions of Mac OS X and many iBook revisions. If you go to the Apple menu at the top left and select "About This Mac", you'll see information on which version of OS X specifically, what speed your iBook's processor is, and how much RAM you have installed.
Be aware that according to Firefox's system requirements, you need the following in order to run it:
At least Mac OS X 10.4
At least a Mac with a G3, G4, G5, or Intel processor.
