The Web Developer Extension does a fantastic job of helping anyone develop for the web. Need to turn CSS style sheets on and off? Need to turn a form from a GET to a POST? The list goes on and on. Anyone that develops for the web should have this plugin as for as I'm concerned.
The stats from w3schools.com are an intersting read, especially if you use it to track the rise of Firefox/Mozilla. Seems like a 150% augmentation since same date last year...

One of the great features about the Opera browser is the quick searches that can be made by typing a shortcut in the address bar. For example, "g searchterm" searches Google.com for the search term.
While Opera come pre-loaded with some great shortcuts, some are missing (namely, an IMDB search would be nice). There is no native UI to edit these shortcuts. This is where the The Opera Search.ini Editor comes in. It allows you to graphically edit the search shortcuts and can integrate into Opera to allow you to add new searches.
