Leaving here some notes (note these are notes from the stations where one click set as default does not work due to Microsoft rollout): From my understanding there are two issues: 1. one issue is that Firefox sets itself as default for the `.htm` and `.html` after clicking the `Set as default` from the Firefox side (this happens only the first time after a fresh Firefox .msix installation) 2. the second issue is that the Firefox message does not show as the default browser in about:preferences even if it's set as the default browser. Installing Firefox 122.0b1.msix from the archive today for the first time reproduced only the first issue from above one time. After changing again the default browser to Edge and back to Firefox.msix I could not reproduce the issues mentioned above on the same Firefox installation. Note this is .msix installation from the [archive](https://archive.mozilla.org/pub/firefox/candidates/122.0b1-candidates/build1/win64/multi/), Idk how this behaves with an official Microsoft sore installation. Please see the attached screen recording that is made on the first ever Firefox 122.0b1 MSIX installation on this Windows 11 station: [link1](https://drive.google.com/file/d/1bgayOE85G4oTExgUMc3g-gdDyF-8jZNe/view?usp=drive_link) and [link2](https://drive.google.com/file/d/1f5tZCQVPdim9_6fQG_oIdABhcDbaLdn3/view?usp=sharing). [Link2](https://drive.google.com/file/d/1f5tZCQVPdim9_6fQG_oIdABhcDbaLdn3/view?usp=sharing) shows that Firefox 122.0b1 MSIX no is no longer hitting issues 1 and 2 after the default browser is changed at least once on the same .msix installation. However, if Firefox .msix is uninstalled and another browser is set as default and then following the STR from comment 0, all the above-mentioned issues will be back again and the second issue will be reproduced indefinitely. This screen recording is made after uninstalling Firefox 122.0b1 .msix and reinstalling it again: [link](https://drive.google.com/file/d/1sB14ehK5ROUQ78cv6VHPtf2Hv5N5cTZm/view?usp=sharing). I hope that this helps. Bogdan will retest this on the Microsoft store version as well when he is back from PTO. This was tested on a VM and a native Windows 11 23H2 station and the results were the same.
