Created attachment 8793922 [details] scroll bar in 48.0.2 vs 49.0 starting with the official linux build of Firefox 49.0, the scroll button doesn't get disabled when there is no more scrolling possible in that direction, as it should be. see attached screenshot comparison between 48.0.2 and 49.0
I just noticed: this only affects the vertical scrollbars, not the horizontal ones
Ty for the report! Could you use the tool Mozregression to narrow down a regression range. See http://mozilla.github.io/mozregression/ for details (mozreg is a python 2.7 package). Run the command mozregression --good=48 then copy here the final pushlog from repository mozilla-inbound.
Unfortunately, mozregression doesn't seem to be able to recover from temporary connection issues (just gets stuck at x%, even though Internet connection comes back after 30-60 seconds), so I can't use this on my flaky connection....
