1995264 - [meta] Evaluate if we can remove the IE importers, and if so, do it.

Status: RESOLVED FIXED

(Firefox :: Migration, task)

Description

[:Gijs (he/him)]

We have a bookmarks importer (which uses the registry and the "Favourites" folder) which I can only assume is no longer used by any MS stuff post-Edge; a history one (which imports typed URLs from the registry and uses a C++ thing that is using Windows APIs to ask for history); and a windows vault form/password importer.

Are any of these still usable on modern Windows 10/11, and do they contain values of interest?

Mike, do you know?

As far as I know, they don't.

Do we know if the IE compatibility layers in Edge still use these things? Do you happen to know, handyman?

Comment 3

I don't know, I can only guess. From looking around, it definitely seems that the Credentials Manager is still available, even on Windows 11, but it's not used by much -- mostly sysadmin operations (in particular, not by Edge). I doubt IE compatibility mode does any non-page behavior differently. I'd guess that all of this stuff is Chromium behavior and isn't affected by compatibility mode.

In that case, then yes, I think we can probably start by disabling the migrator by default, and if we don't hear any complaints or discover that it's needed for other things, we can go ahead and remove it.

IE importer is gone - we're done here!
