In Firefox you can pick keywords for your bookmarks. I find this very useful for quickly loading websites.

Once the bookmark has a keyword, you can type this into the address bar and press Enter and it will load the site. In this example, I have a bookmark for TV listings at Zap2it. All I do is go to the address bar, type “tv”, press Enter, and the site loads.
I do this for “weather” for weather.com, “usb” for usbank.com, “char” for copypastecharacter.com, “wp” for our WordPress login, and many others. I find it much faster to just type these short keywords in the address bar than typing them manually or picking them from a bookmark list.
You can also apply tags to bookmarks which allow you to use the address bar to search for them. However, it won’t let you simply type the keyword and press enter to load the site.
