For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar. I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image). It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window. Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.
