I use this gesture since Tab Kit days (old Firefox 3.x extension)

I've been always looking for a way to do something like this. Makes it so much more convenient to go back and forth between tabs. If you're lazy like me with navigating using the home bar arrows or the alt+arrow keys, this is for you.

Avid Opera user here. I was like handycapped without this feature. Thank you so much for this extension!

I went too long without reviewing this, but it was the one thing I was looking for in a browser before I switched off of Opera a few years ago. This works perfectly.

I loved the feature from Opera GX and wanted it after switching to Firefox. This extension gives exactly that feature, although it's a shame it doesn't work on some pages blocked by Firefox itself.

Dude. I mean... C'mon you people, start with the recognition and respect this man deserves.
Thanks again man.
Firefox without you is okay, however, powered by your stuff... that cool browser turns into a very serious tool.
Respect!

PERFECT. iam upset to see only 36 people using .This extension is deserve better

Does exactly what it states in the description. Very handy feature for mice that lack buttons 4&5.
