I recently noticed that I cannot open the last closed tab (the selection is there, but is greyed out). Then, when rebooting, I notice that the system does not restore the last visited tabs - even though that selection is made in the Options. I recently installed KeePass and it's extension in Firefox and it seems to work well (I don't actually use it often). And, recently I had a glitch where the system would resize my pages (as if I was holding the Ctrl key down while scrolling. Several reboots fixed this issue - but now I can't resize by holding the Ctrl key and scrolling (although holding Ctrl and tapping the - key will resize the window). Any ideas on how to fix this without a total reinstall? I've been copying my Firefox profile from one computer to another for years and am concerned about losing my saved data/preferences. Thanks in advance!!! - John
