Status: RESOLVED WORKSFORME

(DevTools :: Debugger, defect)

Description

[684sigma]

I noticed a problem in Firefox Nightly 55.
When setting specific breakpoints in browser toolbox, devtools stop working normally. Here's how to reproduce the bug:

1. Open this url in a new tab - data:text/html,<audio controls>
2. Open browser toolbox, set breakpoints in file resource://devtools/shared/DevToolsUtils.js, lines 49,50, blackbox the file
        49    Services.tm.mainThread.dispatch({
        50     run: exports.makeInfallible(executor)
3. Open normal devtools on the page, open inspector in normal devtools

Result: Inspector displays everything except <audio> node.
Expected: Inspector should show <audio> node: not only breakpoints shouldn't affect this, but also the script is blackboxed.

Does this still happen?

Honza could you try and reproduce?

Could not reproduce, blackboxing seems to work for this now.
