Hi $h@hith,

I'm telling you the steps for firefox 26.0.

1. Tools->Options->Privacy
2. under History field click the drop down button next to "Firefox will" label, Select Use custom settings for history.
3. uncheck the "Remember search and form history".

You are done, now firefox will not remember any username previously entered in any Social Networking Site.

And you can remove previously saved username and password from:

1. Tools->Options->Security
2. Click Saved Passwords button and Remove all.
