Is this a known problem? As in FF opening up like a new start each time. I have to use sync to reload Add-Ons (AB, Lightbeam), and to restore bookmarks.

Or what else could be doing it?

Thanks.

All fine here with W10 and FF. 😕

Is it just Firefox?

Is your hard drive full?

Just Firefox. 60G used, 330G spare. Might it be malwarebites taking a dislike to FF?

Ah, k. I was wondering if it was profile related.

That’d seem unlikely TBH.

Try an uninstall / reinstall maybe?

Is your login account an Admin account? I’ve had odd behaviour when installing software in a limited account, might need to reinstall, but run that installer as admin.

Guess you do have it set to pick up where you left off on start?

Thanks all. I’ll wait for a rainy day to follow that profile fix, meanwhile can try a reload in case FF has shot itself.
