If you have arrived on this page, I am sorry. I am sorry that you have been added to the thousands of Firefox users that have been crippled by a bug in their latest build. I am a Firefox | Lubuntu Linux user and have been happy to use FireFox for many years. This was a show stopper for me and unfortunately made me look elsewhere for a solution.

We have a discussion page to investigate the challenge further: Tech Support

I have followed through a lot of forum pages to get a result and the majority tell you to try in safe mode. If that doesn’t work, reinstall the video drivers. (WTF).

This seems to be happening too often to too many people to be video drivers unless all video drivers are wrong including windows and Linux drivers????

Try Safe Mode:
If Firefox is open, you can restart in Safe Mode from the Help menu:
Click the hamburger menu (top right 3 lines), select (?)HELP, Select restart with addons disabled.

If the problem exists as it did with me, even in safe mode; you know that it is not being caused by extensions, themes, or hardware acceleration.

One option is to roll back to the stable version: https://ftp.mozilla.org/pub/firefox/releases/52.5.0esr/, you may have to find your language version and also some rollback/installation instructions on the net. (LINUX)

If rolling back is not an option for you, try another browser.

It was a show stopper for me. I have been an ambassador for Firefox for a very long time. Very disappointed. Reinstalling a prior release seems to be the preferred fix. This has it’s own problems of continuously telling you that the software is out of date.

This drives me nuts to the point of installing Opera for Linux as an alternative. I must admit I am enjoying using Opera more than I expected. It is now my preferred browser for lubuntu. I definitely don’t get the problems of being out of date and crashing that I get from Firefox and Chrome.
