Firefox freezes and stops responding even after reinstall
Hi, I've been a Firefox user for a decade, despite three attempts to switch to Chrome. But this is getting on my nerves. I'm in the middle of something and suddenly the browser freezes - I can move the cursor over whatever bookmarks, menu items, tabs or content but nothing responds. It's exactly as if the entire browser had turned into a printscreen. I get no crash report afterwards, I just close and restart it. This has been going on for quite a few months now. I'm using the latest version by the way.
Extensions I use: Adblock Colorzilla Diigo Toolbar Evernote webclipper Fireshot Pin It buton Video Download helper Wisestamp Lazarus Form Recovery
And quite a few other plugins.

Hello kutez, try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
also, any luck if you delete in your profile folder the User.js file you have ?
The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then delete the User.js file, to see if the problem goes away (some programs create and write in the file also).
thank you
Just to let you know, the mouse programs can still respond even when other programs have locked up.
I'm having a similar problem after installing Win 10 Firefox hangs and not responds at the most inappropriate times (often a min after fully loading a page) even after using the Refresh Firefox feature and after reinstalling, in safe mode and not......
