SlashdotMozillaNewsJesse’s Bookmarklets Site – It’s a little known fact that most modern browsers will execute javascript that’s typed into the addressbar. This is not hugely useful in itself, but it leads to a rather wonderful result. If you bookmark the javascript then it can be executed at your whim. Jesse Ruderman has some great examples. My favourite has to be the ‘test styles’ bookmarklet which allows me to apply CSS rules to any page that I’m looking at. This could conceivably be used to alter the look of ugly pages that I stumble across, but it’s primarilly useful for design. I found this quite delightful to use when I was cleaning up some sloppy design descisions earlier today.
