Version 0.1.6 worked more correctly. The icon was better too. Version 0.1.7 does not close the window after restoring the tab. Firefox 70.

TO THE DEVELOPER (SUGGESTED NEW FEATURES):
1) --You must allow the user of your addon to just left-click the mouse button once on your icon to have the most recent site opened. As 99% of the time, when I use this addon, I want to simply open quickly the last tab that I closed.
--And use double-click of the left mouse button on this addon icon to open the list of opened tabs to choose to open.
2) Make the icon that shows on the top of Firefox in white to be able to see it better than the grayish color that it has at the moment and that completely disappear on the dark blue that I have for the top of my browser.

I put 5 stars as soon as you implement this vital feature 1.

Thanks for sharing this addon.

Used to open any tab from any window. Now, although you can see the list of recent tabs in any window, you can only open tabs in the same window it was in to begin with.

Ужасная версия 0.1.7, которая испортила это расширение полностью.

The installation process informs the user that the add-on "requires permission to: "Access Browser Tabs" when asking whether to proceed with the installation, but it does not go ahead with adding the permission itself with out asking anything other than whether to install the add-on, it does not ask whether it should add the permission on behalf of the user, "Access Browser Tabs" is not among the set of permissions that can be enabled or disabled under. Settings-Apps→Permissions, and as for as I can tell there is no mechanism on my Samsung Android 9 tablet for providing that permission. I suspect that absence of this permission is the reason that no undo takes place and no closed tabs are displayed as undo candidates (or as anything else, for that matter).

Obviously this has worked on some systems ( it could not have earned so many stars in the past, otherwise), but there is some assumption that has been made about the way permissions are set that has ceased being true for at least some recent versions of Android (including the Android version running on my tablet (manufactured mid -2019 and updated mid-May to the March 2020 software revision).

Edit: I forgot to mention: I've been running an up to date version of Firefox, updated today to 68.8.1

This addon does not work anymore - if you clear history and clear browsing cache it works again, but I have to keep clear the data to keep this addon working - simply give this rate as useless.

It was great but it just stopped working.
Error is: "Nothing to Restore!"
I'm using FF 75.0.

Does not show any closed tabs on android. Should not be available to install on android.

"Clear all history" button looks dangerous (or just very annoying if you have backups), as others have pointed out, but still hasn't been removed.

The best one among all the extensions of this kind.

Life saver

Suddenly stop working... I can see only "Nothing to restore!" :-(

Edit:
It starded work. I did not change anything only wait, because I believed, If it suddenly broke, It shoud in the same way suddenly fix, so It was happen... Why It was occured, I don't know...

Doesn't work correctly on multiple windows. Opens random tab at times.

Doesn't work on mobile Firefox.

... I accidentally clicked the god damn Clear History button, and without confirmation or anything, this addon just deleted everything. Why does it even have that option?? It should at least give a confirm window before deleting 100% of your browsing history. omg

needs a dark/black mode
