Status: RESOLVED DUPLICATE of bug 1551773

(Toolkit :: Startup and Profile System, defect)

Description

[Sergey Galich [:serg]]

User is unable to use Firefox when profile folder is removed.

STR:

1. Install Firefox from Microsoft Store (probably same for regular distribution)
2. Open it so profile is created
3. Close Firefox
4. Delete C:\Users\<username>\AppData\Local\Mozilla\Firefox\Profiles\<profile folder>
5. Delete C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile folder>
6. Open Firefox

Actual result:

Dialog "Your Firefox profile cannot be loaded. It may be missing or inaccessible." with only one button OK that closes the app.

Expected result:

Dialog with some extra button to create a new profile (or select other existing profile).

I don't think there's anything particularly MSIX-specific about this; it's pretty easy to confuse Firefox about the state of the profile configuration. Given how unusual deleting these profiles in this manner will be, I'm marking this as S3. If there's a more common sequence of actions that will result in users find themselves in this situation, let's re-evaluate.

The Bugbug bot thinks this bug should belong to the 'Toolkit::Startup and Profile System' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Yes, this bug does not have to do with MSIX package. I could reproduce it with a regular build.
