Inform users that "forgetting a browser" means that the linked mnemonic will not work

[Tbaut]

Because we call everything interchangeably a "backup phrase/mnemonic/recovery key", and because they look the same (a suit of words), our users may expect them to perform the same and let them access their directory.

Now a browser backup recovery key is actually different, it is half of a mnemonic. The other half sits in the store on the Tkey network. If both are accessible (meaning the saved browser has not been deleted from Tkey store, and the user has the recovery key, then they can get access to their file using it).

This is all too complex to explain, but we should make a better job at informing our users of the risks at least. I'm suggesting to show a popup to confirm the deletion of a browser we could tell:
"You are about to delete a saved browser, any browser recovery mnemonic that was downloaded will not work any more, do you want to continue?".

I think this would be small enough for users to care reading. And if they don't.. then at least we tried.
