Works, but because of the Tab Unloading Feature the tabs need to be in RAM. If you have much RAM, disable Tab Unloading in mozilla:config browser.tabs.unloadOnLowMemory or use a "Refresh all Tabs" Plugin.

It needs a Hotkey.

Dark mode please!!!!

Very good! This should be part of the default apps! Useful when working with several open tabs to hop from one to another tab. Please keep up the good work!

Unfortunately other reviews are right, just opens a blank tab. Firefox 98.

it works fine, but can appear to hang when some of the browser tabs have to be reloaded: in this case opening every tab and wait for the page reload would then make the overview work again. so apparently the addon should trigger this reload (if this is possible by the api). maybe you want to open source this addon, so others can help. thx for your work.

Im Firefox 70.0.1 seh' ich da nur eine leere Seite wenn ich auf das Icon klicke.
