Frozen debugger after breakpoint activation on remote debugging. about debugger

This is happening with multiple sites not only this one.

This is the error message in the Browser Toolbox.

Testing on Firefox Developer Edition.
Fenix Nightly 71 is still in a weird state.
BUT the debugger on Firefox Dev Edition is at least working. 70.0b13 (64-bit)

@wisniewskit ran into that issue too on webcompat/web-bugs#42325 (comment)

@karlcow, thanks for the report!

When loading http://walmart.decipherinc.com/survey/selfserve/53a/wal18001 I see:

We appreciate your interest, but unfortunately this survey is now closed.

Do you have any other test page we could use to reproduce the bug on our machines?

[karlcow]

@janodvarko It breaks but in another way now.

• tested on macos firefox nightly 80
• Remote debugging activated
• Android 10 Firefox Nightly 80.

1. Go to http://walmart.decipherinc.com/survey/selfserve/53a/wal18003
2. Go to debugger
3. Activate Event Listener Breakpoints: "click"
4. Tap on Continue at the bottom of the page (the debugger opens)
5. click { } at the bottom of the window

The full debugger becomes white, all the context is lost.
click reload on the desktop browser top bar, reload the debugger

@karlcow thanks, the STRs is great help!

I can reproduce the issue clearly.

I cloned the bug into bugzilla:
https://bugzilla.mozilla.org/show_bug.cgi?id=1652679

We want to stop using this issue list and archive this entire repo eventually.
The source of truth is Bugzilla and m-c
