My question is: where does one find this option in the preferences for Safari Version 7.0.3 (9537.75.14)? I cannot find this option anywhere: not in Mac OS X System Preferences or in Safari’s own Preferences. I would love to be able to save the passwords for these sites, so that I don’t have to keep regenerating and re-remembering them.
Manually enter your username and password. Tap "Passwords" right above your keyboard. Tap "Save This Password." It still won't autofill when you first load the page, but now you can tap in the username field and hit "Autofill Password." There seems to be no way to actually reset the "Never for this site" setting. Sounds like a job for http://apple.com/feedback.
Since you have multiple questions here, I would attempt to answer one of them:
In case of Firefox:
Open the permissions manager
in the address bar type following about:permissions and hit enter
In the new window select the web site to work on and choose the settings.
To further customize a specific web site (fine tune) click on the small Icon in front of that website address. In the new pop up window you can highly customize what that web site can and can not do.

It's gone. Use this extension to work around it: http://ozymandias.me/2013/05/08/force-autocomplete-on-in-safari/
