Very small scrollbar which you can't click.png
STR: (Nightly 43.0a1 (2015-08-20))
1. Open attached page
2. Open devtools-Inspector
3. Click (ev) button next to <body>
4. Open any Event Listener code
5. Try to scroll inner code with [press left mouse button on scrollbar, then move mouse]
Result: It's impossible. The outer list is scrolled
Expectations: There should be a way to scroll like that.
It's not specific page. I see that in the field every day.

Summary: Scrollbar of dark theme can't be scrolled with left mouse button in some cases → CodeMirror editor inside event popup can't be scrolled with left mouse button (with dark theme active)
More about it:
With dark theme, scroll bar can be handled in most part of UI (devtools-Inspector) except in some part:
===
1.Open devtools-Inspector
2.Click (ev) button next when available
3.Click on a script to unfold it and see see see Event Listener code
4.Except the fact the scroll bars are way too transparent and hard to see most of the time, you can NOT grab them to scroll [press left mouse button on scrollbar, then move mouse]
5.But if there is list of lots of event listener script, you can grab the scroll bars to browse through that list. It works in that case.
===
1.Open devtools-Inspector
2.Go to the CSS editor tab
3.You can NOT grab them to scroll [press left mouse button on scrollbar, then move mouse]
===
1.Open devtools-Inspector
2.Go to the Debugger tab
3.In the code panel, you can NOT grab them to scroll [press left mouse button on scrollbar, then move mouse]
===
Every other Code mirror editor like sytlish code editor are affected by this BUG.
===
Please fix it and make the scroll bar for dark theme larger and more visible (more opacity)
===
setup:
Windows 10x64
Firefox 49.0 x64
(In reply to fremea from comment #3)
What you described is mostly bug 1100622 + bug 1265807. The latter is recent regression (Firefox 48)
THIS bug only covers the case with "lots of event listeners".
