F1 is a browser extension that allows you to share links in a fast and fun way. Share links from within the browser, from any webpage, using the same services you already know and love. Mozilla F1 is made by Mozilla Messaging.
Share with your favorite services
With support for Facebook, Twitter, Gmail, Google Apps, Yahoo Mail and LinkedIn, we have your favorite services covered—and we're adding more services with every release.
Once you've installed F1 sharing is as easy as...
1 Hit the F1 icon in the URL bar
2 Choose your service in the menu
3 Express yourself and hit share!
*Firefox 3.6 support: F1 uses some advanced technology
and UI capabilities that are not possible in Firefox 3.6 and earlier.
If you installed the previous version of F1 that works with Firefox 3.6,
it will continue to work while Firefox 4 is in beta. Once Firefox 4 is
released, the older 3.6 compatible extension will be phased out.
