How to Fix Firefox Not Responding ?
1. First try to Restart Firefox by simply selecting File menu and clicking “Quit Firefox”. If this doesn’t work restart your computer after repeating this step.

But this may remove your extensions and other configurations and customizations (website permissions, DOM storage, device settings, Toolbar customizations for example).
You may also have to change back the accessibility configurations. But the good news is that, a folder “Old Firefox Data” will be created in this process, so in case the refresh doesn’t work, you’ll be able to restore your information by simply copying your files to the newly created profile.
3. Another simple option is to clear cookies and cache . In the ‘Tools’ menu selects the option ‘Clear Private data’ and then ‘Clear Private Data Now’. Your download history, cache and cookies will be cleared.
Go to the Library button, select History, and click ‘Clear Recent History’. Here you also have an option to select the time range for which data or history has to be cleared. You can select both Cookies and Cache and click ‘Clear Now’.
4. Try restarting Firefox in Safe Mode. It will disable all extensions and themes which will return to the previous state when you leave the safe mode. Some settings will get reset and hardware acceleration will also get turned off temporarily.
You can enter the safe mode by selecting Help button from the menu, click on ‘Restart with Add-ons Disabled…’. A Firefox safe mode dialog will start up now.
you can just press down the ‘Shift’ key while starting Firefox.
In the dialog box click ‘Start in Safe mode’. Now select ‘Refresh Firefox’ which will restore Firefox’s factory default state. If the problem persists it is possible that the problem lies in any extension, theme or hardware acceleration.
Now to exit the safe mode, click exit mode from Firefox menu. Then start Firefox normally. It may also happen that Firefox will get stuck in the safe mode.
5. Check Extension settings. Sometimes it may happen that extension settings override Firefox settings. To check this, click the menu button and then Add-ons, select Extensions. Here, by clicking Options button you will be able to find out any suitable option which may solve your problem. Click the required option, Save it and then Restart Firefox.
6. Reinstalling Firefox is one of the final solutions if you are not able to solve the issue. This will require the complete removal and installation of Firefox. But don’t worry, your Firefox profile data will not be removed, as the information like bookmarks and passwords is stored in different location.
To start with, close the Firefox running currently (select Exit from the File menu). Now download the latest version of Firefox from mozilla.com. Next step is to uninstall the current version of Firefox from Add/Remove programs ( you can find this option from the Windows Control Panel). Don’t forget to back up your data before proceeding. In the Windows Program Files, there is an option of delete the ‘Mozilla Firefox’ folder, choose this option and delete the folder. Now delete the Firefox profile folder. Install new Firefox version. After the installation is complete, a wizard will open showing “Import Settings and Data”. A new profile will be created now. You can now recover the back up data. Also reinstall your extensions and themes.
