Firefox has a feature called keyword bookmarks. It's an incredibly handy way to do fire off many different searches. Most of them boil down to using Google's site: operator, but it's still a big timesaver to not have to type the whole "site:blah.com -inurl:blah" thing in, especially when you have multiple "inurl:" search terms.
An alternate way to accomplish this is to use the ctrl+up/down feature of the search bar to select the search method you want. I haven't tried that, but I'd imagine it's slower.
