Firefox stucks for a while when launched

Hi!

I've just unstinalled Office 2013 from an Office365 subscription. Since then, Firefox stucks for a few seconds when launched (cant type or interact with Firefox for 4-5 seconds).

I've removed Firefox completely, deleted the Profile folders and registry keys and installed a fresh copy. The problem still presists. I've launched Firefox in Safe Mode and the problem also appears there.

What I did then was to "Reset Firefox" to its default settings. The problem then seems gone, but on the next launch of Firefox, the issue is back.

All my plugins are set to "Never activate". I've removed the two Microsoft Office Plugin .dlls too for testing purposes, but none of them fixes the issue.

Thanks for your help! Cheers, Tom

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.


It is possible that your security software (firewall, anti-virus) 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:


Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
