I also want to add, if you can, disable "auto complete" or just ignore it and just type the whole URL, if you do not trust browser add-ons.
Bookmark the site you want is a good alternative also. It's safer and more comfortable for the user, as people are lazy to type (I am at least)
Nope, this is not a good idea. The bookmarks can be altered and hackers know people trust their bookmarks. This false sense of security is exactly what these hackers/criminals want. In some browsers you simply click on the favorite bookmark and edit the URL section
A hacker simply search for the keywords in the registry and replace that with the phishing site URL.
