Since upgrading to the latest edition of Firefox, pages will load extremely slowly and then after a few moments, it crashes. I have looked through all of the troubleshooting steps, such as uninstalling and re-installing, trying to disable addons and trying to start in safe mode, but the latest edition of Firefox crashes before I can do any type of diagnostics. I have never hade this issue before until upgrading to the latest version. I am not sure what to do since Firefox loads the page extremely slowly, then before I can try to troubleshoot it crashes.

You can use one of these to start Firefox in Safe Mode:

  • On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
  • On Mac, hold down the Options key while starting Firefox
  • Help > Restart with Add-ons Disabled

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need close and restart Firefox after toggling this setting.


Do a malware check with several 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.
