Manual Proxy
I had a proxy set manually before and it was working just well, after I updated firefox it stopped asking for username password for my proxy and I keep getting no network error on every website I check. I also reentered the proxy data again and checked somethings in the about:config page to be true but still doesn't work.

Hello
1. If it's not prompting you, you may need to force it.
Clear Saved Credentials:
Go to the Firefox menu (≡) > Settings> Privacy & Security > Logins and Passwords > Saved Logins.
Search for your proxy address and remove any saved entry for it.
or/ and check
2. Settings for autologin
Go to the Firefox menu (≡) > Settings > Network Settings > Button Settings and
Ensure the checkbox "Do not prompt for authentication if password is saved" is not checked.
