Other Ways To Solve This Issue-

• There could be a possibility that you aren’t using Firefox correctly. There could be many tabs opened that are utilizing Java, Flash, etc. Press Ctrl+Shift+Esc and it will open Task Manager so that you can take a look at the memory usage of Firefox that is under Processes.

  It should not exceed 500-700 MB, even if there are multiple tabs opened. Do not open more than 20 tabs at a time as Firefox sends inactive pages to the Virtual Memory of Windows.

• There could be an extension of Firefox that is slowing down the browser with useless RAM.For this boot the browser in Safe Mode. Then go to restart with disabled ADD-ons. This should solve the issue.
• Do not clutter the Page File by running on too many games or starting a disk defragmenter, running MySQL, running Visual Studio 2013/Eclipse, etc. while you have more than 10 tabs active. There can be cache timeouts that may cause memory and disk access to slow down very much or totally stop that can cause the “Firefox Not Responding” errors.

  The browser gets tired of waiting for the page to be loaded from disk and gives up. This can also happen when the space on the disc isn’t enough where the Page File is situated. This can be solved easily by searching for “Virtual Memory relocation in [windows version]” to move them, on Google.

• At times, Disk fragmentation can be the issue behind causing the Error of “Firefox Not Responding”. Fix the size of your Pagefile so that it doesn’t cause a load of unnecessary reads/writes or to cause file resizes. You can take a look at the HDD’s fragmentation state. Go to My Computer and right-click on any disk. Click on Properties. Click on the Tools tab find disk defragmenter. Check your disk to resolve the issue.
• Lastly, you may be having a malware on your system. You can use an anti-virus. If you already have then you can be ensured if that is the case or not. At times antivirus is also no a full protection. So it is better to check all options.
