Whenever I open Firefox, it asks for User and Password for proxy authentication.
It hasn't an option to save the User and password of authentication as other programs.

Reproducible: Always

Steps to Reproduce:
1. Set up a proxy that requires authentication.
2. Open the Firefox
3. A authentication window will appear asking for User and password of the proxy.
4. Close Firexox and reopen.
5. Appears the authentication window again in blank
Actual Results:  
Whenever I open Firefox, appears the authentication window again in blank, forcing me to put the data forever.

Expected Results:  
An option to save the authentication data in Firefox, this way we does not need to put the data forever.
