So I was using ff as always, after I closed it and lunched again it started to freeze and switched to 'not responding' over and over. It takes very long time to navigate across ff and load websites. I tried refreshing, reinstalling, disabling hardware acceleration and add-ons - no effect. Everything works fine in safe mode though. I scanned system with antivirus - nothing. Any clues on my case?

Update on bitdefender issue . If you update Bitdefender does the problem go away ?


Bitdefender FREE AV version was recently causing crashes and hangs in Firefox 53. Sometime yesterday the Bitdefender people rolled back their problem update of Bitdefender. If you make sure your Bitdefender is fully up to date then as far as we know at present that should not have bad effects on Firefox.

I am having the same issue. It started 5-8-2017. I have uninstalled and reinstalled firefox and refreshed it a couple of times too and nothing has helped. I have the paid version of bitdefender, total security 2017. I am using a laptop with windows 7.

If you are having issues with a paid for version of bitdefender please

  • Report the issue to Bitdefender to ensure they are aware of the issue.
  • Make sure you are updated to the latest version.
  • State what product (Full title & version) you are using.
  • Test with Bitdefender enabled and disabled and confirm that makes a big difference.
  • Please include some comment about the severity of the issue and the symptoms you are seeing.
  • Are you only getting slowness, or do you also get crashes ? if so please let us have a CrashID from the latest crash report: visit about:crashes the string starting bp- is needed. Please see Troubleshoot Firefox crashes (closing or quitting unexpectedly)

I am making the assumpti0n that Bitdefender commented about the Free version and updated the free version because they are only aware that it is the free version that causes problems.
