My bookmarks and history are gone and cannot be restored after AdobeFlash update.

My grandmother installed an update to Adobe Flash, however there were "extras" that got downloaded along with the Flash update. Since then, she has lost her bookmarks and history and any new bookmarks/history is not recorded. At first, she received an error message that her bookmarks and history were being used by another program and could not be accessed, so I removed all those extra programs that came with the Flash update and her bookmarks/history returned. Then she received a message along the lines of "The Bookmarks and history system will not be functional" which cleared up after a reboot. Now nothing seems to work. I tried restoring them from a backup but it said it was unable to restore. As a last ditch effort we do have an Old Firefox Data, but it's from 2014 so I'd like to try getting her more recent stuff back before resorting to the old data.

One should have nothing to do with the other.

Let's try this first;

Flash Player: remove it using these links; http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html Uninstall Flash Player | Windows http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html Uninstall Flash Player | Mac

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?


Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
