Because I didn't use it as much as thought I would, I decided to remove the Portable Apps Suite "container" from my USB drive and simply keep the portable programs I use the most.
Therefore, I pulled my entire "FireFoxPortable" folder to the desktop, removed the Portable Apps Suite by formatting my USB drive, and promptly dragged the FireFoxPortable folder back to my USB drive.
I thought that, since it's the exact same folder I have been using for months, that my profile, bookmarks, extensions, Greasemonkey scripts, etc. would all work the same as before.
