Moving from Windows 8 Release Preview to Windows 8 Retail Release


I moved user profile folders to my retail copy of Win8. My startups (I start TBird when the system starts) imported - and amazingly Thunderbird started up from the startups even though I hadn't installed it.

Then I installed Firefox, and it immediately booted up and asked if I wanted to restore my previous session! There was no previous session in the Retail - but it was the session from my copy of the Release Preview.

My questions are

"Is this a feature of Mozilla products, or a happy byproduct of storing program info/settings/etc in the AppData folders?"

"Will I lose my info if I remove the old hard drive with the Release Preview - or is everything stored in the AppData folders?"

It seems that you restored your profile and yes, all the info is in your profile so you should be good to go. You can call it a feature :)

Best, Ibai

Profiles need to be registered in the profiles.ini file to make Firefox find and use them.

You can click the "Choose folder" button in the Profile Manager when creating a new profile to make Firefox use a specific profile folder.
