Firefox has announced the winners of the Extend Firefox contest where developers submitted Firefox extensions that would make life @Firefox more easier for users. The contest saw more than 100 entries being submitted and finally the winners were announced, here are the list of winners and our favorite picks from them.

Pencil a GUI prototyping and diagramming that everyone can use, Tagmarks for one click bookmark tagging and HandyTag a automatic bookmark tagging add-on won in the best new add-on category.

Read it later which saves pages of interest for later reading, TagSifter which lets you browse your bookmarks by their tags and Bookmarks Previews which adds a album view and thumbnail view to the bookmarks manager won in the Best Update add-on category.

And the best Music add-on goes to Fire.fm a add-on that provides direct access to the extensive music library on Last.fm, well there were no other contender in this category, but Ping.fm is really good.

Coming to the focal point, we have our own favorites among those who won, or came out as runners up, here are the extensions we loved from this batch of winners (and runner-ups).

Read it Later Well this is a extension we love, why? Because there are sites we may not want to bookmark, and put off only till we find some time to catch up with, think about it as a sort of temporary bookmarks, totally love it, since we come across several great articles at work which we may want to read when we get home.

Close’n Forget Though this plugin did not feature as a winner, for us this is a definite must have. Come on, the only (maybe) reason people clear cache and history is to avoid someone from seeing some sites they visited (for NSFW or other reasons), this extension allows you to do just that, though without clearing your entire cache, so you can open a tab, browse to your heart’s fill and close and forget everything about it, including cookies, cache and history too.

TagSifter Why we love it, simply because looking at simple text in our bookmarks (1000s of those) does not make us know where this is from, having a previewing system definitely helps, when it comes to browsing those bookmarks.

Tagmarks Who does not love tags, and for those who loves tags what would be much better than having a one click way of bookmarking them.

Fire.fm Last is not always the least, and with Fire.fm we couldn’t find a more better way to use the phrase, this is probably one of the best add-on for music lovers, who want to hook up Last.fm content into Firefox, simply awesome.

So what do you think about the winners this time around? Do you have your own favorites? Do share them with us.
