Firefox Community Forum

I just tried to open Firefox and got the message "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". DO NOT redirect to this link

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

Hello,

Today I was forced to reinstall my PC (nothing worked, a lot of problems etc). I was told that I don't need to use any backup for Mozilla (even if I wanted, my PC problems would not allow me to do that) because yesterday I've made a sync. After couple of hours of reinstalling the system I wanted to sync my account to get back my Bookmarks and turns out that sync does not restore them. I have all my plugins and that's all, none of the bookmarks. I've lost literally years of saved data.

In the Add Bookmark menu that is accessed from the address bar, the field for adding a keyword shortcut is absent. This is the same menu that is accessed by Ctrl + D. It's ironic that the menu accessed via a keyboard shortcut is missing the field for adding a keyboard shortcut.

"Tags" field is present on all, but I find it orders of magnitude less useful than keywords.
