Mozilla has announced the winners of its third "Extend Firefox" contest, an annual competition that recognises the year's best Firefox add-ons.
This year's contest, which launched in March and brought in more than 100 entries, focused on add-ons that took advantage of Mozilla's newest open-source browser, Firefox 3.0.
Mozilla unveiled the final version of Firefox 3.0 in June after a long series of alpha, beta and release candidate versions.
The company awarded three grand prizes in the "Best New Add-on" category to Pencil , a diagramming and graphics interface tool; Tagmarks, which adds additional tagging icons to Firefox 3.0's location bar; and HandyTag, an extension that provides relevant keywords for associating with bookmarked sites.
In the "Best Updated Add-on" category, Mozilla also pegged three winners, including Read it Later, a bookmarking substitute; TagSifter, which lets users browse bookmarks by their tags; and Bookmark Previews, an extension that adds album and thumbnail views of bookmarked sites.
It's not surprising that many of the contest winners add functionality to Firefox's bookmarking; Mozilla revamped the tool by adding an integrated search engine, single-click bookmarking and other features.
Mozilla also singled out Fire.fm in the "Best Music Add-on" category. The extension lets users access the music library on Last.fm, the UK-based Internet radio website.
The winners in the new add-on group will be given travel and accommodations to the Mozilla Developer Day of their choice, as well as new Apple MacBook Air notebooks. The three developers awarded prizes in the updated add-on category will receive a 15-inch MacBook Pro notebook, while the author of Fire.fm will be flown to London to visit the headquarters of Last.fm.
The contest also recognised six runner-ups in the new add-on category.
More information about the contest winners can be found on the Mozilla Labs site.
