Just noticed the other day that i can get a preview of all open tabs in Firefox on Windows 10 taskbar.
Is this a new feature or an addon that slipped this one in?
A mystery for me right now, but a welcome one which reminds me of Vivaldi's similar preview feature.
This, and the DuckDuckGo which can be tweaked in so many ways now, makes me want to go back to Firefox as default.
