I just reinstalled this after a Firefox Reset after the upgrade stampede of 2026 (at least I hope its over ;^). I have found this to be a simple, rugged, reliable tool, time tested over about a decade.

I use it since the beginning, and I honestly can't use internet without it. It doesn't always work perfectly but it does its job!

It works.

Must have add-on, easy and fast way to navigate between tabs.
Thanks to Richard for the help.

Lightweight but does exactly what I need. Perfect!

I tried the preference "toolkit.tabbox.switchByScrolling" before (switch tabs by scrolling on tab bar), which works in principle, but stops working as soon as there are many tabs and the tab bar itself becomes scrollable (i.e. exactly then, when the functionality to change tabs by scrolling becomes most useful).

Have just tried on Ubuntu 16.04 & FF67.
Works nicely.
I was also used to TabWheelScroll so the gesture at first seems awkward but actually I like the fact there is NO need for keyboard.

Thanks a lot !

In the old versions, the Tab Wheel Scroll was nice, but it works. Thanks for the plugin.

This was a godsend when MileWideBack stopped working. I did get something similar and I think possibly a port of MileWideBack to the new extension framework, but it wouldn't work on Linux because the Window Manager placed some sort of 1px border that ruined the whole scheme of "stick your mouse to the left side and scroll to move through tabs".

TabScroller offered a ridiculously simple alternative that has relieved me of all that frustration. This kind of tab scrolling is a must for me now and I love that there's a simple and robust way to do it with this extension.

Works as advertised and makes a very nice addition for speeding up tab-switching. The only downside being the interruptions on pages where right click could not be captured, but those seem rare. The explanation of the required permissions is also much appreciated.

Works as expected!

Прекрасно работает !!! рекомендую.

Thanks for bringing this feature back to life !
Would it be possible to assign another button than mouse right to activate the scroll ?
Not the most convenient with laptops...

I can do the same, but without thу right mouse button. Firefox Quantum.
