Scrolling doesn't work inside (all) web pages
Scrolling doesn't work inside web pages, but it does works when navigating between tabs (when all of them can't be shown at once). The problem occurs when using Gnome with Xorg and doesn't happen in FIrefox Developer Edition, or when using Gnome with Wayland.
Scrolling doesn't work even in safe mode and with hardware acceleration disabled (as proposed by this link).
I use Arch Linux with Gnome 3.36.5 X11. You can ask for more information if needed.

I forgot to say: scrolling with the bar still works, it's just mouse scrolling that doesn't work
I fixed it myself. The problem seems to come from an external source, not Firefox. The fix I used was to install the imwheel package. If you ever have the same problem, I suggest you take a look at this great thread.
The fix was to use this package called imwheel. For more information look at this thread.
