top sites/highlights vanished and I can't access my email (I can on internet Expl).
Everything has vanished. I've tried all suggested fixes. I even deleted Firefox and installed again. I continue to get the same error msg..."the bookmarks and history system will not functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I'm using Webroot and have not made any changes ...period. Any help would be appreciated. Thank you. Scott

If you use Sync then best is to disconnect Sync temporarily during troubleshooting.
You can check for problems with the places.sqlite and favicons.sqlite files in the Firefox profile folder.
- use "Verify Integrity" button on the "Help -> Troubleshooting Information" (about:support) page
If errors are reported with "Verify Integrity", close and restart Firefox and retry.
If "Verify Integrity" cannot repair places.sqlite, rename/remove all places.sqlite and favicons.sqlite files in the Firefox profile folder.
Firefox will rebuild places.sqlite and restore the bookmarks from a recent JSON backup in the bookmarkbackups folder.
- keep a backup copy of places.sqlite in case a new places.sqlite database has to be created
