Firefox will not open because it thinks it is open, but task manager says it is not open.
I cannot get firefox to open. If I try to uninstall it says I must close it. If I try to download it it says I must close it.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.
NOTE: Establish a habit of exiting/closing Firefox with Firefox button > Exit or File > Exit to allow an orderly shutdown of Firefox and closing of all of the files that Firefox has open.
- Stop the Firefox process:
- Mozillazine - Kill application
- Windows 7 users click here
- Mac users: http://techheavy.com/2011/02/the-mac-task-manager/
- Why Firefox may hang:
- Firefox hangs (see Hang at exit)
- Firefox hangs (Mozillazine) (see Hang at exit and Closing Firefox properly)
- Firefox is already running but is not responding
- Use Firefox Safe Mode to find a problem with an Extension or Plugin:
- Don't check anything when entering Safe Mode, just continue
- If the problem does not occur in Safe Mode it is probably an Extension or Plugin causing the problem

I too faced this issue sometime back, and it happened while i was trying to change/run Firefox with a different profile. Try this it should atleast open your browser
1) goto Run and type "firefox.exe -profilemanager" [or firefox.exe -P]
When it asks the you can try creating a new profile or try with the existing ones
2) Browse to C:\Users\"Your user_name"\AppData\Roaming\Mozilla\Firefox
Once there delete the 'Profiles' dir and also the 'profiles.ini' file.
Then try repeating STEP 1 above and create a new profile when asked
In worst case give the machine a restart and repeat from STEP 1

CAUTION: Prabhuti's post
Deleting the Profile folder (following step 2) in Prabhuti's post will delete all of your personal information (passwords, bookmarks, extensions, customizations). This should not be done. Only as a last resort is establishing a new Profile usually necessary. Keeping the old profile allows the user to retrieve certain important information (passwords, bookmarks) and copy them to the new profile.
The path shown in step 2 is not the path for XP.
The result of Prabhuti's post is starting clean like the initial installation of Firefox.
