Password Remember Button does not function; Can't input 3rd Party Passwords for Social Networks/Emails.

Question

My "Remember" button doesn't work. Simple as that. The "Not Now"
Button still works, and closes the pop-bar. Remember doesn't do anything.
[Exception... "'User canceled master password entry, login not added.' when calling method: [nsILoginManagerStorage::addLogin]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsLoginManager.js :: anonymous :: line 445" data: no]
Occurs when trying to input 3rd Party extension passwords.
I have no master password set, I have also read the "Password not remembered topic", and it didn't help.
Error Console yields this:
"'''Warning: The 'charCode' property of a keyup event should not be used. The value is meaningless.

Answer 1

Okay, I have started Firefox in Safe Mode, and the Remember button still didn't work. After checking the error console, It had the following message again:
"Error: uncaught exception: [Exception... "'User canceled master password entry, login not added.' when calling method: [nsILoginManagerStorage::addLogin]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsLoginManager.js :: anonymous :: line 445" data: no]"
After I Evaluated it (In the error console) it gave me a slightly different version:
"Error: missing ; before statement
Source File: javascript:%20Error:%20uncaught%20exception:%20[Exception...%20"'User%20canceled%20master%20password%20entry,%20login%20not%20added.'%20when%20calling%20method:%20[nsILoginManagerStorage::addLogin]"%20%20nsresult:%20"0x8057001e%20(NS_ERROR_XPC_JS_THREW_STRING)"%20%20location:%20"JS%20frame%20::%20file:///C:/Program%2520Files/Mozilla%2520Firefox/components/nsLoginManager.js%20::%20anonymous%20::%20line%20445"%20%20data:%20no]

I read the Troubleshooting extensions & Themes, but It didn't help.
When I tried to read "http://kb.mozillazine.org/Password_Manager" I get a page that says:
"ERROR
The requested URL could not be retrieved
While trying to retrieve the URL: http://kb.mozillazine.org/Password_Manager
The following error was encountered:
* Connection Failed
The system returned:
(110) Connection timed out
The remote host or network may be down. Please try the request again.

Also, this error occurs in ALL 3rd Party extensions. It can't log me into E-Mail accounts, Facebook, Twitter, anything. The error message has a window title of [JAVASCRIPT APPLICATION] if that says anything.
