I just found my new favorite Firefox add-on (extension, plugin, whatever). Using the Google Calendar “Quick Add” Firefox Add-on, press “cntrl” + “;” and your Google Calendar “Quick Add” box will popup in the middle of your screen no matter what tab or page you’re on.

So, you heard about a great event on Twitter? Hit “cntrl” + “;” type in the event and you’re done. I love it!

If you use Google Calendar you need to know about the “Quick Add” feature. It’s by far the easiest way I’ve ever seen to enter an event into a calendar. Somehow it can magically parse dates, times, locations, and even repeating events out of a one line description. It understands things like “every Friday,” “next Tue.,” and “noon – 3” Check it out in this short video demo to get the idea.

Unfortunately, as of this blog post, the Google Calendar “Quick Add” Firefox Add-on isn’t compatible with FirexFox 3 beta. 🙁
