Just freezes. no idea. I've been using Firefox on safe mode for 4 weeks now and today even in safe mode won't quit. the 2 problems did not happen at the same time. This is only on my account on this computer, not on the others. Tried these suggestions on the mozilla troubleshooting support pages. clean reinstall, deleted my profile folder deactivated preload pages in the about:config preferences network.dns.disablePrefetch (no result, reactivated it ) cleaned cache, ... could it be my synch ? I activated it only recently.
