Since I installed Firefox 17.0.1, the program has become unstable. I have a hard time getting the program to respond to start. I have to try at least 3 times

As I mentioned, the program will not start on the first time that I click the icon. The hourglass appears for a second or two and then disappears. I have to try at least 3 or more times before the program responds. Should I try to uninstall 17 and reinstall 16. I have already uninstalled 17 and reinstalled it.

Chosen solution

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.

See:


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 an existing profile to the new profile, but be careful not to copy corrupted files.
