[Environment:] Windows 8.1 / Mac Osx 10.13 [Steps:] See STR. from https://bugzilla.mozilla.org/show_bug.cgi?id=1499388#c0 [Actual Result:] When taken over by dedicated logic, Custom Profile Name is overwritten. [Profile1] Name=default-2656FF1E876E9973 IsRelative=1 Path=Profiles/49v8sw31.zzzz [Expected Result:] Taken in consideration that there was a discussion about making the dedicated profile names more user friendly, I think the first step would be fixing this issue, which means that we should use the existent profile name + the installation hash. e.g.: for the above example, the dedicated profile should look: [Profile1] Name=zzzz-2656FF1E876E9973 IsRelative=1 Path=Profiles/49v8sw31.zzzz I'm not very confident about this, but I would also have the channel added to this naming logic. It's kinda'of backwards, but in this way, we would align profile naming logic to dev-edition. So for the above example, we'd have something like: [Profile1] Name=zzzz-2656FF1E876E9973-beta IsRelative=1 Path=Profiles/49v8sw31.zzzz

I can update the logic so it only renames the profile if it is currently named "Default" (or "dev-edition-default" on dev-edition).

This is fixed locally.
