Breakpoints do neither set nor work after new version

[TomGo71]

Coming with the new version today, the breakpoints do not set anymore or do not work in firefox/visual studio code respectively.
If I want to set any breakpoint, a message is popping up to set the mapping path. If I click yes, a new mapping path is inserte into .vsconfig, but it's the same like it's already configured in .vsconfig. So the same path is set now twice.
The breakpoints do not work anyway.

I use the lates versions of firefox and visual studio code.

This should be fixed in version 2.10.1.
If it doesn't work with that version either, please add the following to your launch configuration, start a debugging session and try to set some breakpoints:

"log": {
    "fileName": "${workspaceFolder}/vscode-firefox-debug.log",
    "fileLevel": {
        "BreakpointsManager":"Debug",
        "PathConversion": "Debug",
    },
},

Afterwards, post the contents of the log file here.
