Tested on FF74:
Go to "about:config" and set "toolkit.tabbox.switchByScrolling" to true.

Solution I found for this feature recently, using no addons or third-party software:

In Firefox 57+, I use AutoHotKey script to replace this addon:

Script has exactly same functionality - it switches the tabs by mouse wheel when cursor is over the tab bar - no need to hold right button or something.

I started using Waterfox for now. That browser is like old Firefox; old extensions work =)

Until this addon is updated, I am using TabScroller.

This user has a previous review of this add-on.

I love this add-on so that I go back to 52 ESR instead of 57

it's my first time to review an add-on. This add-on is the most important one for me. Thank you so much for doing such a great one and it will be missed. <3

5 stars for the extension... except in FF57 in wich it's not working anymore.
As mentioned here (see below posts from WakeUp and from Anonymous 4 days ago), I had to use Autohotkey to get a kind of solution. However I had to replace the Tab key by the Page Up/Down keys.
(I'm using it with the excelent "Tree Style Tabs" extension, for vertical tabs)
Here it is :

#IfWinActive ahk_class MozillaWindowClass
;MouseGetPos, [OutputVarX, OutputVarY, OutputVarWin, OutputVarControl, 1|2|3]
~WheelDown::
MouseGetPos X, Y
if ( X < 205 )
SendInput ^{PgDn}
Return
~WheelUp::
MouseGetPos X, Y
if ( X < 205 )
SendInput ^{PgUp}
Return

Мне приносят дискомфорт широкие полосы прокрутки, а этот плагин позволяет сузить их до нескольких пикселей, за что я его и полюбил. Пожалуйста, обновите его поскорее для firefox quantum

Unfortunately, it is not possible to support Firefox 57. Mozilla has refused to add the necessary replacement APIs for Web Extensions.

Loved this addon so much, pity it can follow with new Firefox. The AutoHotKey thing works but it's very hacky (e.g. if you place the tabs on the right the script has to change for x > 1680 or so, and then this only works to the right of the window.

I switched completely to firefox when chrome faced out NPAPI and killed my favorite extensions, and now again I lost another of my core functionality add-ons with this "new update" of firefox 57.
Thanks to the author of this wonderful piece of code, is sad to see it go.

SOLUTION FOR THE TIME BEING.

1) Get Autohotkey
2) Create the following script:

#IfWinActive ahk_class MozillaWindowClass
;MouseGetPos, [OutputVarX, OutputVarY, OutputVarWin, OutputVarControl, 1|2|3]
~WheelDown::
MouseGetPos X, Y
if ( X < 225 )
SendInput ^{Tab}
Return
~WheelUp::
MouseGetPos X, Y
if ( X < 225 )
SendInput ^+{Tab}
Return


Adjust the X value to the width of your vertical tab bar (if you are using a horizontal tab bar (you shouldn't), change to Y < 33 or similar. Auto-run the script with Windows. Voila! My life is complete again.

You can use an autohotkey script as an alternative https://autohotkey.com/board/topic/71017-chromefirefox-tab-switching-with-mousewheel/

Vale Tab Wheel Scroll.

I want you to know this was one of the main reasons I kept using Firefox for so long.
