1569145 - about:debugging - PopUp Autohide - devtools are unusable

Status: RESOLVED DUPLICATE of bug 1569410

(DevTools :: about:debugging, defect)

Description

[Serge]

Attachment: DevTools.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

Win 10x64, Nightly 70.0a1 (2019-07-25) (64-bit)

• Open about:debugging.
• Navigate "This Nightly" - try to debug any installed extension (via Inspect button)
• about:devtools-toolbox?type=extension... opens
  Enable "Disable PopUp Autohide" and select desired frame to inspect.
  Every popUp (even the ones from devtools itself) remain open.

Actual results:

If Disable PopUp Autohide is selected every popUp (even the ones from devtools itself) remain open.
This leads to the inability to hide popUps, click on any buttons (including close window button). For some reason a doubleclick (instead of a single) is needed to expand any element is Inspector.
User ends up with unresponsive devtools with multiple opened popups and inability to close devtools via close button.
The only way to close them is via Windows TaskManager.

The issue occurs on any extension, creating a clean profile also didn't help.

Expected results:

Disable PopUp Autohide should affect only elements that are related to the extension (and chosen frame)

Thanks for filing! Sorry I missed it and filed a duplicate bug the next day. I already added a needinfo request on the other bug, so let's move the conversation there. Hopefully I can get something done in release 70.

Thanks!
