Firefox is already running, but is not responding? Simple answers don't seem to be working

Question

I started Firefox earlier today, and got a message about a Firefox issue and that it needed to be reset. Since the other option seemed worse than reseting, and Reseting Firefox seemed relatively painless, I clicked okay. A brief message popped up about successfully saving passwords, bookmarks, etc. Then a smaller window appeared, saying it was cleaning up Firefox. During that, the process seemed to freeze up. I closed it out, killed any firefox processes running, and tried to restart Firefox, when I got the "Firefox is already running, but not responding." message. There's a folder on my desktop labeled "Old Firefox data" which I assume came from the Firefox Reset (There's also now a copy of the profile on my desktop, just incase).

I found this and have been trying to work through it, but it doesn't seem to be helping.
1) Ther'es no Firefox.exe in my taskmanager, nor is there a plugin-container process.
2) I deleted the "parent.lock" file in both the profile (Which is just a bunch of jumbled letters and numbers with "default" in it), and the Old Firefox folder. However, these files were just "parent.lock" not "parent.lock.parentlock"
3) I didn't change the name on it, so unless the reset did before it locked up, I have no idea what to change it back to.
4) Its not a file share, so...
5) This might be a possibility. The Firefox folder that my profile is in is "Read Only" but I can't seem to change that. Everytime I go in, unselect "Read Only" and tell it to propagate the change through the subfolders, it seems to work, but when I check the properties 10 seconds later, "Read Only" is checked again.

Sounds that the profiles.ini got corrupted when removing the old default profile and adding the new profile.

You may have security software that was preventing Firefox from making changes to the file.
You will have to use the Profile Manager to either restore an existing profile or create a new profile.
A "Reset" creates a new default profile with a time stamp appended and tries to import some settings from the old profile leaving the old profile intact, including the (invalidated) cache folder (about:cache) that can take up to 1 GB.

Firefox 15+ versions will move the old profile folder to an "Old Firefox Data-##" folder on the Desktop that gets a number appended if you use reset more than once, so you can no longer use the profile manager to revert to the old profile.
