I love Firefox because I can pretty much customize it anyway I like to suit my tastes. Besides the add-ons and themes available, Firefox even allows you to change how your browser functions. The key to this is the ‘about:config’ command that you type in the address bar.
With Firefox 2, I use about:config to plug many of Firefox’s notorious memory leaks. The tips I used worked great and I never had any problems with my Firefox. A little while ago though someone posted an interesting question on Lifehacker that I hadn’t really thought about. What if you want to delete an about:config entry?
This is quite a practical question. Let’s say I misspell an entry as I’m typing it in. Obviously, I don’t want to keep these useless entries in my browser so I would get rid of them. The good part is that there’s a very simple way to delete redundant entries without causing any chaos with your browser.
To delete an entry, just right-click it and select Reset. Then, restart Firefox. If the value you chose was originally part of the browser, it will go back to its default value. If the value was added by you, it will be deleted.
I tried out this trick on my own version of Firefox with a few deliberately mistyped entries. It worked fine for me. This is a handy trick to know in case you ever make some unwanted adjustments to Firefox. What do you think of this tip? Do you know of any other way to delete about:config entries in Firefox? Let me know in the comments.

1. Close firefox (so not to mess it up even more).
2. Go into your profile page “%AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\” the x’s stand for a randomly generated code for every profile.
3. Open the file “prefs.js” in a text editor.
4. And just use the find tool and enter the title of the string. (not the whole title just a part if you want) and just erase that part.
