This is interesting. My guess is that this is not MSIX specific. I think we should add this as an item for testing with :mhowell's patch for Bug 1709969.

NI to Molly just so she's aware of this potential issue.

I can reproduce this on a non-MSIX build, yes.

I think I may know what's happening. The implementation of the remove button in about:profiles (which is this profile service function) doesn't seem to have been made aware of dedicated profiles; along with the profile's directory, it removes the profile's old-style Profile* section in profiles.ini, but it does not remove the profile's Install* section or its entry in installs.ini. Manually removing those two sections does lead to the expected behavior of a new profile being created during the next startup of the affected build, instead of the profile manager appearing.

This is not an MSIX-related bug, and I don't think it's serious enough to block shipping the MSIX, so I'm removing this bug's dependency relationships and moving it to the appropriate component.

I think this bug will have existed since at least bug 1518587, possibly even further back.
