Hello. We verified that the `Firefox is already running and not responding` message is displayed by opening Firefox MSIX on a clean environment while Firefox.exe is already running. Testing was performed on Windows 11x64 with 95.0a1 (2021-10-18) MSIX and .exe builds. However, we encountered two scenarios regarding this and we don't know if they are expected: 1. When Clicking the` Close Firefox` button when the `Firefox is already running` message is displayed, the message closes and then reopens every time when the `Close Firefox` button is pressed. 2. Closing Firefox.exe while the `Firefox is already running` message is displayed and clicking on the `Close Firefox` button afterwards opens some Firefox instance that does not have updates enabled and no migration is performed. If this Firefox is pinned to the taskbar, then closed and reopened the migration is performed and the MSIX build is displayed. Attached a screen recording covering both scenarios: [link](https://drive.google.com/file/d/1QmAPHD84TaYK2X5PhHGyehVawh0ZZvtu/view?usp=sharing). Thank you!
