I suspect a user.js file. (Okay, your "More System Details" says you have one, so no psychic powers are involved.)

Check out the user.js portion of this article and see whether that helps: How to fix preferences that won't save.

Thanks Jscher2000 for replying I have gone through the link and have changed user.js file, Lets see if I face the problem again or not by tomorrow
