Status: UNCONFIRMED

(DevTools :: Debugger, defect)

Description

[posilejte.spam]

Attachment: addon 2.zip

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:96.0) Gecko/20100101 Firefox/96.0

Steps to reproduce:

Load my temporary addon (the addon src is attached) in about:debugging
Go to a link where a content script of the extension should run: https://www.youtube.com/watch?v=HuIb3XTQVJw
Open developer tools (f12)
Look for the script being listed in the Debugger

Actual results:

In Firefox 96.0b6 (Developer Edition) the script doesn't appear in the Debugger.
Note I used the same addon in both browsers.

Expected results:

In Firefox 95.0 (release) the script appears in the Debugger

Also please note that I installed Firefox Developer Edition an hour ago, so the profile is new

Hopefully it is clear that Firefox 95 displays the script correctly whereas Firefox Developer Edition does not

The Bugbug bot thinks this bug should belong to the 'DevTools::Debugger' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Thank you for the report!

I can't see any script in the Debugger that would be loaded from the extension.

Alex, what could be wrong here?

Many things were fixed around content script in latest version of Firefox Nightly (Firefox 136).

Would you mind giving it a try again? It works for me when testing the attached addon.
You should see a new menu in the debugger source list, with a "show content scripts" item.
(this is wired to devtools.debugger.show-content-scripts preference if you prefer the about:config way)

It works now, when I set devtools.debugger.show-content-scripts to true, I saw the attached temporary addon, as well as all permanently installed addons.

Each addon appears in its own category (same icon as main thread), to mark that it is a separate process (unlike when the bug was filed), right?
Inside that category, the content scripts are shown correctly :)

However now in that UI, there is a weird behaviour, where there are duplicated addon entries (permanent addons). Either Dark Reader is launched in more processes, or it is a bug. See picture
