Research direction
Start with the attach-mode instructions in the README and reproduce the configuration using a globally incorrect firefox.executable setting. Trace how the attach launch reads that setting and produces the error; done means attach mode no longer requires an unused executable, or the message clearly identifies the global extension setting.
Written by the indexing model from the issue text.
Description
I am getting the Couldn't find the Firefox executable when launching in attach mode. I am asking myself now if this is a wanted behaviour, since I wouldn't expect that the executable is needed for that.
Background
I was following the instructions for launching in attach mode in the README.
Accordingly, I have set up a launch.json that contained the recommended block:
{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to localhost",
"type": "firefox",
"request": "attach",
"url": "http://127.0.0.1/"
}
]
}
My firefox had the necessary about:config changes and launched fine in debug mode with
"C:\Program Files\Mozilla Firefox\firefox.exe" -start-debugger-server
When I launched the debug session in vscode with this configuration I got the Couldn't find the Firefox executable error.
Cause
The firefox.executable config was set globally to a wrong location.
Two things that I think would have improved my situation
- the error message would point out that this is set in the global extension settings
- the error would not be thrown since (correct me if I am wrong) the executable is not called at all in
attachmode
