Good add on but if there is a firefox tab like settings, history, or even a new tab open the add on doesnt work and just stops so if you have any new tabs open it doesnt allow you to scroll over them but its probably for security. It does state that this is a limitation. Also the only buttons that you can use is shift, ctrl, alt, right mouse button and meta which is fine for me but might be limited for some people. I recommend this though and its great to use just firefox kinda limits it true potential.

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!

Very cool.

On my Mac I set it up so that the Ctrl plus Option plus Command keys ("Control Alt Meta" in TabScroller preferences) to first be depressed before I can use the two finger scrolling to scroll through my tabs.

And I also set the number of milliseconds, in TabsScroller, to be 180. This gives a nice feeling of slowness when I move through my tabs this way. Otherwise it defaults to zero which is a little fast and flickery.

Thank you Richard Anthony Burton, Firefox extension developer, for programming this. And for making it free. I often times have a lot of tabs and I am usually bouncing between a group of four and this helps me to jump between those and to synthesize those tabs' contents to make a decision.

It works.

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

Does not work for me in Win10 and FF87. tried evey button option, but the tabs won't scroll with the mouse wheel.

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 !

Can you change key combination to "shift key+mouse wheel" ? Current [right click + wheel] makes tab switching action damn awkward. If you dont't want it to be default, then provision as an option would be equally nice.

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

It can be implemented without holding button: https://forum.manjaro.org/t/howto-enable-tab-switching-in-firefox-using-mouse-wheel/39954

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.

Nice (y)

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.

i hold down right click, i press right click, i hold down left click, i uninstall, i reinstall, i reset my computer i reset firefox and this app STILL doesnt work. i had hoped this was like the previous tabscroll addon from the previous versions but its so much worse. in the old version you only had to hover over the tabs and scroll. please fix.

Update to authors response. Your addon literally states "A simple addon that does one simple thing. It allows you to scroll through your tabs with the mouse wheel, while holding the right button down" so when you cannot scroll through your tabs with the mouse wheel while holding the right button down (which thats not clear either a developer should be a little be more specific than "right button" but i used both right on the directional arrows and right click) then the add on is a failure. It seems YOU have not read my review and are reacting at a bad review. If you dont want bad reviews then have a working add-on. If your add on doesnt "allow you to scroll through your tabs with the mouse wheel, while holding the right button down" then why advertise it??

Hello, but why other add-ons work with dial/home page, or add-on page ?!!

Move Tab Hotkeys works on thoses pages and keyboard key is captured.
