I want to reset Firefox, and the message is that something is preventing the reset. I have closed all open windows and I still get the "Oops" message,
I have uninstalled and reinstalled Firefox because I was receiving unwanted adware and was being directed to untrusted sites. Now I want to reset Firefox because I want to change the home page and toolbars, and something is preventing the reset. I have closed all open windows repeatedly, but the problem continues.

You have malware on your computer, go to your start menu & search "Uninstall a program" and find a program that you never installed.
The most common are
- Search Protect
- V9
- Conduit Search
Note that the OP is using a Mac computer and is not on Windows.
Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem
Check the programs that are on your computer
Windows: Start > Control Panel > Uninstall Programs. Mac: Open the "Applications" folder Linux:
- Ubuntu Unity {web link}
- Xfce: Applications Menu category sections
- options depends on the package manager and the desktop environment
Go thru the list. If you find something that you don't know what it is, use a web search.
