Your Firefox profile cannot be loaded. It may be missing or inaccessible.

[ilmoralito]

when trying to launch the debugger, after a while I get the message Your Firefox profile cannot be loaded. It may be missing or inaccessible. and then the message Error launching configuration \n connect ECONNREFUSED 127.0.0.1:6000

I first tried to specify the profile directory via profileDir but got the same message. Then I try to specify the name of the profile but I get this message in the console

Debugging session ended unexpectedly
Debugging ended

Could you help me how to solve this behavior?

Same issue, four months after OP's post. Is anyone still working on this extension?

PR #200 shows the "tmpUrl" property. I set tmpUrl like this:

{
  "request": "launch",
  "type": "firefox",
  "reAttach": true,
  // "preLaunchTask": "npm: start:refresh",
  "name": "Launch localhost (firefox)",
  "tmpDir": "${workspaceFolder}/.vscode/firefox-tmp/",
  "url": "http://localhost:1234/",
  "webRoot": "${workspaceFolder}",
}

It launches firefox now.

For people facing this bug, can you tell us what's your OS and what version of Firefox you're seeing the issue in?
