Steps to reproduce:

Tried to import from my existing Edge profile into Firefox via the "Import Browser Data" function in the settings.

Actual results:

An error dialog appeared stating "Firefox couldn’t find any programmes that contain bookmark, history or password data."

Expected results:

Firefox should have presented me with a list of things to import.

Also, whenever I click the Import button, there's an error emitted in the browser console.

DOMException: PathUtils.join: PathUtils does not support empty paths
    getDataPath resource:///modules/ChromeMigrationUtils.sys.mjs:347

Looking at the referenced line, the function is trying to open the platform specific location of where the other browsers stores the user profile, looking at the paths stored just before the error location there's this comment in the Linux specific paths section.

// Edge is not available on Linux.

It's a bit out of date.

The Bugbug bot thinks this bug should belong to the 'Firefox::Bookmarks & History' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thank you for the report and for providing the details. Marking this enhancement as New.

This patch allow Firefox to read $HOME/.config/microsoft-edge/ to import Edge's
data, including passwords, histories and bookmarks.

It seems like Edge canary, Edge beta and Edge dev's data can be import in the same
way, but I don't know their paths and if it works, and I cannot test it. Should I
add these?
