Firefox is so slow it is practically unusable, also on Mozilla Support pages!
Many pages cause the system to freeze for a long time so the application needs to be ended with the Task Manager (which always reports that the application is not responding). I have downloaded the newest version of Firefox (16.0.2) and i have reset Firefox. I have also tried starting without add-ons, but it does not help. I am unable todetermine which plug-ins i really need and which I could delete.

More Information
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
