Cannot resolve disappearance of my bookmarks toolbar
I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.
"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

This has been an issue for years, apparently, and has been addressed here on multiple occasions. A comprehensive article is here https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional. This gives directions on how to fix, hopefully. The "why", best I can tell, is corruption of sql databases, the cause of which above my paygrade but is often attributed to unexpected shutdowns, like crashes and such. Good luck.
