Debugger doesn't work in Firefox developer edition [version 125.0b9]

[Abdelhafid01]

I have approximately the same issue with the debugger in firefox developer edition (version 125.0b9) doesn't have effect, it doesn't work at all. so I swith to firefox normal edition (version 124.0.2) it works partially and I don't know why it is stopped and have the issue in debug console which tells me: SyntaxError: import.meta may only appear in a module

NG0912: Component ID generation collision detected. Components 'NavbarItemMenusComponent' and 'NavbarItemMenusComponent' with selector 'bl-navbar-item-menus' generated the same component ID. To fix this, you can change the selector of one of those components or add an extra host attribute to force a different ID.

TypeError: au.shift is not a function

here my launch.json config: { "version": "0.2.0", "configurations": [ { "type": "firefox", "request": "launch", "name": "Launch firefox", "reAttach": false, "url": "http://localhost:4999", "webRoot": "${workspaceFolder}", "firefoxExecutable": "C:\Program Files\Mozilla Firefox\firefox.exe", "profileDir": "C:\Users\Abdelhafid.CHETOUANI\AppData\Roaming\Mozilla\Firefox\Profiles\p0g2jmlu.default", "firefoxArgs": ["-private", "-purgecaches"] }, { "type": "chrome", "request": "launch", "name": "Launch Chrome against localhost", "url": "http://localhost:4999", "webRoot": "${workspaceFolder}" } ] }

And with Chrome and Edge the debugger works nicely.

I also am not having any luck on MacOS with the same dev version of FF. It doesn't work at all.

its not working for me either plugin version 2.9.10 with firefox developer edition 126.0b9 and this launch config takes forever to open then shows a white tab and gives me all kinds of exceptions but cant load the page

works fine without the debugger, or with debugger and chrome

{ "type": "firefox", "request": "launch", // "reAttach": true, "name": "Launch FF", "url": "http://localhost:8100", "webRoot": "${workspaceFolder}", }

This seems to be resolved, it works for me now:
