Undoing 'Recently Closed Tabs' no longer available - please help!
I find myself unable to access the 'undo closed tab' option, which I have previously found so useful. When I go to History > Recently Closed Tabs, the Recent Closed Tabs entries are greyed-out. How can I reactivate this essential functionality please?

-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select Restart with Add-ons Disabled
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update Firefox to the latest version by going to Help Menu -> About Firefox -> click Check for Updates -> if an updated version is found then download the latest version and install it. After that follow these steps:
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> click the Favicon on SearchBar -> click Manage Search Engines -> select all Unwanted Search Engines and click Remove -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

Make sure that you do not run Firefox in permanent Private Browsing mode.
- https://support.mozilla.com/kb/Private+Browsing
- You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
- To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history
- Deselect: [ ] "Permanent Private Browsing mode"
Thanks for your reply. I can confirm that Permanent Private Browsing mode is not selected. Firefox is set to record all history. However, the 'Undo Closed Tabs' options are still greyed-out in the history menu. What could be the reason for this? How can I change it?

I disabled a number of Add-ons. I found that it was one in particular which had been somehow prevented reopening closed tabs. It's called Split Browser. A useful Add-on, but one which it seems I will now have to disable. Thank you for you helping me diagnose the problem. Your help is much appreciated.
