Go get it! Try it out. Notice the Geode and Improved Ctrl+Tab interface :) Firefox now also has built-in Ogg video support and ability to drag-n-drop tabs from one window another. Have fun with it (i.e. test it and report bugs). More feature to come in near future. Here’s a link to their What’s New site for Ff3.1
After my love and over-joy for Mozilla’s Ubiquity, here’s another Mozilla project that I feel energized about. It’s called Bespin. Bespin is an online IDE. Currently it only supports CSS/HTML/JavaScript syntax highlighting, but its architecture allows for further additions. If you have worked with vi or vim, Bespin UI will look very familiar. It is almost as if Vi team made a Web version of the software.
I am looking forward to a beta and post-beta launch. It is going to be EPIC! If you would like to try it out, feel free to create an account and try your hand at it. It is sure to amaze and entertain your kindling mind.
Here’s a cheer for the first step towards a usable and free online IDE.
(update: Not sure why I didn’t mention a link to the project. Here it is.)
I’m a big fan of Google’s “define:” functionality (in google search, type define: life to see it). Recently, Google released a dedicated dictionary page, so I thought I’d create a nice little Firefox keyword bookmark to do this from the address-bar itself. And here’s how this works:



Now every time you want to get a definition of something, all you have to do is type define [your_word] in the address bar, and see the most current definition come up!

(NOTE: this snapshot shows address bar with “define firefox” in it, but that will change automatically once you hit return. I just left it there so you can see what to type.)
Google offers dictionaries for A LOT of languages. 
So you may choose to do this with endef (for English definition) spdef (for Spanish) gudef (for Gujarati) and whatever have you!
I hope this helps some of you! Let me know if you come up with some fun hacks of your own :)
