ik wil de firefox 5 installeren, maar de firefox 3.2 wil niet weg.
Zegt steeds er is er al een firefox geopend. Hoezo geopend? Oude kan niet weg!
Try to drag the old version to the trash.
Thank you, but it did not work. I always get the message that I can not open the new one because one is 'open'. Now all my firefox programs are in the dustbin but still there is one 'open'. How?
Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
Thanks, I tried a lot of your things and now it works!
