Help the Firefox community set a Guinness World Record for the most software downloaded in 24 hours by downloading Firefox 3 on Download Day (some time in June).

You can pledge and get buttons and banners at the Download Day Headquarters.

Update 2008-06-12: The date of the download day has been set: Tuesday, 17 June 2008. While you wait, check out Deb Richardson's Field Guide to Firefox 3 to get an overview of all the new features and improvements.

Update 2008-06-17: Today is the day, but Firefox 3 won't be available until 10 am PDT.

While searching for something completely different, I ran into an interesting article on Firefox extensions to avoid. The article was published by Computerworld on 10 April 2007 and discusses ten add-ons that are “bad” because they waste network resources or don’t provide enough benefits to be worth running. The extensions to avoid:

• Fasterfox
• NoScript
• Adblock and Adblock Plus
• PDF Download
• VideoDownloader
• Greasemonkey
• ScribeFire (formerly Performancing)
• TrackMeNot
• Tabbrowser Preferences
• Tabbrowser Extensions

To learn why you should avoid these extensions, you’ll have to read it.

This article complements one published 7 March 2007 on 20 must-have Firefox extensions. It’s interesting to note that in March Greasemonkey was a must have, but by April it became one to avoid. And web developers who don’t know about these add-ons will definitely find them worth checking out.
