[Mozilla Enterprise] browser.migration.version

[Mike Kaply]

That is an internal preference that shouldn't be messed with (it should get
set automatically)

The current version is actually 87 (It is not tied to the browser version).

And an old version should work fine (unless it was a string for some
reason)?
