suddenly a few days ago, firefox crashed and I have not been able to recover it despite uninstalling, reinstalling after debugging, defragging and restoring my computer. I am using norton 360 antivirus software.

Hi,

You can try installing the latest Firefox after uninstalling the currently installed one: https://www.mozilla.org/en-US/firefox/new/

Also, in the security software (Norton, other) installed, you can try deleting all existing instances of Firefox and its related processes/files in all the different configuration modules/areas of the security software like process monitoring, sub/spawned process control, virtualization, HIPS etc., in addition to the security software's main configuration panel. Instead create new fully allowed/trusted rules for Firefox + its related processes in all the different modules/panels - a genuine/original Firefox installer as well as all the installed EXEs (Application) and DLLs (Application extension) are digitally signed by Mozilla Corporation (right-click > Properties > Digital Signatures). Even otherwise, some security software may also ask again when Firefox and/or its sub processes are started, and you may be able to allow/trust at that time. Please see this.

Try to disable hardware acceleration in Firefox.

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 may have a problem with a corrupted or missing system (core) font.

You can use the System File Checker to check if font files are missing or corrupted.
Open a cmd.exe window as Administrator:
Start, click Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
After the cmd.exe prompt, type: sfc.exe /scannow
