Try going into the task manager and end process named Firefox.exe and then open the Firefox, if it won't work then contact me for further details on my mail id hasit.p.bhatt@gmail.com

See http://kb.mozillazine.org/Software_Update (Software Update not working properly) Remove the files in the updates and updates\0 folder: 

C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates
(%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox\updates)

Do a clean reinstall:

  • Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
  • Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
  • Don't remove personal data when uninstalling.
  • It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
