Great addon, have used it for years, I wish the icon was still transparent, however, to work with dark themes and not stand out as much.

How to ruin good extension. Change of toolbar icon was absolutely unnecessary, or at least you should give choice to users to pick between new vivid icon an old transparent icon.

С недавних пор расширение стало открывать не ту вкладку на которую выберешь, а ранее закрытые.

I wish there was no dividing line between the favicon and the title. And, the gap between the favicon and the title is too wide.

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

Все бы хорошо. Но что за ограничение в 25 закрытых вкладок? Хочется, как в других расширениях, побольше

The tabs closed in private windows can be restored on normal windows.
Is this intended behaviour ?
(Win 10, Firefox 60.0.1 64bit)

I found this an an replacement for an TabMixPlus function, does what it says, but the icon is INVISIBLE on a dark background.
a change between a white and dark icon would be great or color option even better. so always have to guess where the icon is.

used to work until last update. i have 5 separate firefox instances, with random number of tabs, Undo Close is always empty ”Nothing to Restore!”

Please remove Clear History menu item, it's absolutely not needed on a regular basis! Or at least make a corresponding flag in settings.
I've lost all my browser history because of that without single prompt! Uninstalling until it's fixed.
It would also be good to add an ability to reopen last closed tab by left mouse click, and to open the list of closed tabs by right click. That way it will mimic the old extension behavior the most.

The "Clear History" button really sucks. No confirmation dialog appeared and all my history were gone.

Why 'clear history' erases the whole browser history without prompt?! It should erase list of closed tabs only or warn / ask for full erase...

Показывает только 25 последних закрытых вкладок, если в настройках выставить 26 и более - не показывает ничего вообще. Надеюсь в будущем исправите, пока тройка.

Why no clear option?

Can you please update this add-on that i thas the same features as the non web extension version?

"Click the image one time to undo the last closed tab. Three times to open the last three closed tabs and so on"

It doesn't work that way, when i click once i get the context menu.
Also the font and icons are weird. Here is how it looks in the advertised picture and how it looks in mine: http://i.imgur.com/XzJT1yQ.png
Firefox Nightly v56

But the last two menus don't work.
