Aza Raskin has put together a short video tutorial on how to turn your Firefox bookmarklets into Ubiquity commands. “Bookmarklets are clickable actions (technically a link containing some Javascript) that can be added to the bookmarks bar of your browser. They’re a good way of getting control of the web back into users’ hands, by allowing them to add whatever new functionality they want to the websites they visit. The main problem with bookmarklets is that they don’t provide a scalable solution for accessing their functionality. You can only have so many buttons on the toolbar before they become unusable.” There’s a new utility function in Ubiquity that makes it trivial to turn any bookmarklet into a Ubiquity command, and Aza’s video tutorial shows you how to do it.

Justin Scott writes, “With the release of the first beta of Firefox 3.1 comes everyone’s favorite release-time festivity: extension compatibility updates! If you’re an extension developer using a maxVersion of 3.0.* or less, please test your extension before declaring 3.1b1 compatibility. Some of the changes for extension developers are listed [at the Mozilla Developer Center]. 3.1.b1 is an allowed version on AMO, but 3.1.* will not be added until closer to final release. Keep in mind that you can always look at the Developer Statistics Dashboard to see how many of your users are on 3.1 betas and may be marked as incompatible/disabled.” For more information you should check out Justin’s blog post.
