After I installed 4.0.1 I can't install add-ons. I have tried to reinstall firefox but it wont help. What is the problem?
My computer: 'Mac OS X' Version 10.5.8 Processor: 2,53 GHz Intel Core Duo Memory: 4 GB 1067 MHz DDR3
When I try to install an add-on, the installation bar won't move, and I can't remove/delete the progress too.
