It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Hi, Sorry for late reply. Things were going ok with add on's off and Hardware Acceleration off. It just crashed now in the same way as before. I put it in safe mode before checking if add on's were in operation. Sorry ! I will carry on and let you what's going on. Once you have disabled add on's will they reinstate when you re start the computer each time ? Thank you for your help Paul

Once disabled, an option/add-on/whatever should remain disabled. Is this not the case with you?

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

The bug report talks about the problem happening while Firefox was updating.

You can try to modify multi-process settings to see if this has effect.

  • set number of content processes to 1 if it is currently set to a higher value (4)
    Options/Preferences -> General -> Performance
    remove checkmark: [ ] "Use recommended performance settings"
  • disable multi-process windows in Firefox

You can disable multi-process windows in Firefox by setting this pref to false on the about:config page.

  • browser.tabs.remote.autostart = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
