Mozilla Messaging team has announced another exciting project: F1. F1 is a browser extension available for Firefox 3.6+, which makes sharing on web an easier task. It also offers experimental support for web publishers / site owners. Currently, it supports only Twitter, Facebook and emailing via Gmail.
F1 is the latest add-on for the users, who love to share web pages on social networking websites. There are already tons of such add-ons (like Shareaholic), even for Mozilla based browsers.
Moreover, this extension offers experimental API support for the publishers who want to experiment with the F1. According to Mozilla, "the F1 Share extension adds a share api to the navigator object, making simple sharing available to any website. This feature can help websites to add share buttons to specific items within a page, such as having a share link for each blog entry within a blog. When the share function is called, the F1 share panel will open allowing the user to select how they want to share the link.".
Install F1 from add-on gallery.
