How do you start Firefox? Does it navigate to a specific URL immediately? Please provide a trace log for geckodriver and if possible a minimized testcase.

Looks to be related to https://github.com/mozilla/geckodriver/issues/2036 where we never got a reply from the reporter.

Also did that start with the Firefox 105 release or was it also present before? If the latter is the case it would be good to know since when it's happening.

Actually this is a dupe of bug 1784593. Nimmy please provide your information on the other bug and we will reopen.
