Since 2 weeks, Firefox and Seamonkey both started freezing when loading the first "real" Tab. "Real" means that they can load the interface and the "restore last session" page, but they cannot load any website without freezing completely. I have to kill the process in the Task Manager.
As far as I see, those 2 don't share any folders (both default installation), the only common thing is that they are using the same rendering engine.
I'm using the latest version as of today in both browsers.
How can I get my browsers back to work? I already tried uninstalling/reinstalling. Did not change anything.
