When `keepProfileChanges` specified, the extension is unable to connect

Is this a feature request or a bug?

bug

What is the current behavior?

Devtools fails to connect with the error:

Error: connect ECONNREFUSED 127.0.0.1:40911
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1595:16)
    at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:130:17)

Error code: ECONNREFUSED

With verbose logging enabled, I see the following message displayed 250 times:

[/home/nobleman/Dev/scheduler/extension/node_modules/.pnpm/web-ext@7.11.0/node_modules/web-ext/lib/firefox/remote.js][debug] Retrying Firefox (1); connection error: Error: connect ECONNREFUSED 127.0.0.1:35935

What is the expected or desired behavior?

Should be able to connect. This is my config:

module.exports = {
  run: {
    firefox: "deved",
    firefoxProfile: "web-ext",
    profileCreateIfMissing: true,
    keepProfileChanges: true,
    startUrl: ["https://app.joinhomebase.com/schedule_builder"],
  },
};

Removing keepProfileChanges: true,, allows it to work again

How did you create the profile directory?

What is the content of user.js and prefs.js within that directory?

[smac89]

@Rob--W The profile was not created by me. I specified the option profileCreateIfMissing: true, and that's what it did; It created one within the current folder.

The folder created only contains a user.js file with the following:

user_pref("browser.zoom.full", true);

Interestingly, today when I attempt to reproduce the bug, I still get the same issue, but with the added caveat that it pops up the "Choose User Profile" dialog. Upon creating a new profile within this dialog, and choosing to open Firefox with it, the problem I described in my previous bug report still persists. After a few minutes of doing nothing, the command exits with the aforementioned error.

I also added the following additional option to the run.pref key:

pref: ["devtools.toolbox.zoomValue=1.30", "browser.zoom.full=true"],
