hello wilna, as the first crash id you've mentioned doesn't seem to work, can you copy a few more of them and paste them into a reply on the forum? thank you...

Crash ID bp-3cb9b20f-34e4--448f-80c3-e88f92141218. My Firefox on my laptop has been crashing for the past two hours. I have uninstalled and re-installed the most recent version (downloaded via my tablet) but I still get no joy

Thanks, everyone. In the end I uninstalled Firefox again, restored my computer to the 15th (last update) and then installed the most recent version of Firefox again. That has done the trick.

I still don't know what went wrong, but at least I'm back in full force! Regards Wilna
