1199876 - [e10s] Breakpoints no longer hit inside actors from Browser Toolbox

Status: RESOLVED WORKSFORME

(DevTools :: Debugger, defect)

Description

[J. Ryan Stinnett [:jryans] (Use needinfo, replies may be slow)]

STR:

1. Open a in-tab toolbox
2. Open Browser Toolbox
3. Set a breakpoint in an actor
  * Such as highlighter.js#pick
4. Use the toolbox to perform an action that triggers the actor's method
  * Such as click the pick element button

ER:

Breakpoint hits.

AR:

No hit.

This is still working in 42, but broken in 43.

Will attempt a regression search soon.

I misinterpreted the results before.

Nothing has changed between 42 and 43.  Instead, the issue is that this fails for e10s windows.  It continues to work in 43 if you open a tab toolbox in a non-e10s window.

I'm fairly sure this has never worked for e10s windows.

And look at that... if you use the Browser Content Toolbox, it will stop.

Using the tools correctly helps!
