Firefox mouse wheel stopped scrolling

My mouse wheel stopped working after upgrading system today. The wheel works fine everywhere else (Dolphin, Konsole (KDE5)), but it doesn't work in firefox. The only way how to scroll now is eother using keyboard arrows, or using scroll bar on the right. Mouse 3 click (the wheel) works fine though. It might not actually have to do with the update, but I'm not aware of any system change I've done, and the wheel works everywhere else, which seems weird.

$ uname -roms && firefox -v
Linux 4.0.7-2-ARCH x86_64 GNU/Linux

(process:1780): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
Mozilla Firefox 39.0

Re: Firefox mouse wheel stopped scrolling

It might be related to smooth scrolling or touch scrolling. Try about:config and search for "scroll". Also try a new FF profile to see if it is either a plugin or a setting.

Re: Firefox mouse wheel stopped scrolling

It was something in my profile. I coudn't figure what it was unfortunalely, but I tried and smooth scrolling was not that. Clean profile solved that. It was a pain to move all the addon preferences over, but in the end, fresh profile is not that bad. It still sucks I don't know, what caused it. From time to time, I still come up to some things I forgot to move over to the new provile and I have to swith to the old one, and the mouse wheel still doesn't work there.
