Scrolling issue in panel when async-pan-zoom enabled in Firefox.

[ZzzZombi]

I know it's still not supported in the stable Firefox channel but I went ahead and tried enabling the new "layers.async-pan-zoom.enabled" setting in Firefox stable to get the new, better scrolling/zooming feature and had no problems with it so far, except this issue.

When the option is enabled if the panel has a scrollbar (has more domains than the height of the panel) scrolling with mouse wheel is no longer possible. Another problem is that right most "block" in the "per-site" column of domain list gets so thin, you can't properly click on it.

If I have understund (I speak bad english) you use the async pan zoom in Firefox stable (39?)
And it's verry buggy, but I don't think that it's a uBlock bug, it's a browser bug, and it's mostly because you don't use es10, async pan zoom need the es10 activated
See : http://www.ghacks.net/2015/07/28/scrolling-in-firefox-to-get-a-lot-better-thanks-to-apz/
I have also read on an article than async pan zoom need the support of OMTC, or OMTC is not currently supported on Linux, so if you are on Linux it's probably the factor.
You must test the amazing New async pan zoom on nightly with es10 or in Firefox developer/aurora instead of Firefox stable.
Sorry if I have bad understund your message and please don't add browsers bugs on the uBlocko issues, gorhill have already an gigantic lot of work and he have not the time for this :/

Thanks. It's most likely related to not having e10 enabled in stable channel yet.
