Who does not know what this <extension is - I recommend
to try it if you often share various links with colleagues / friends via social networks. The f1 extension was released in November last year in order to simplify the placement of various kinds of links on the web. We all saw buttons like “share this”, but they are not always convenient, and often too lazy to use them for one reason or another. But the F1 extension is quite convenient to use. So, the other day Mozilla has updated its design and functionality.
The new design of the extension visually separates one service from another, so that visually nothing can be confused, and to use each service is quite convenient. In addition, F1 supports a large number of social networks and other resources, where you can share with your friends found material. The list of supported services includes LinkedIn, Twitter, Facebook, Gmail, Google Apps and Yahoo. Yes, for some Russian-speaking users, such an extension does not quite fit, due to the lack of social networks in the
contact user’s usual domestic
contact , but there's nothing you can do, there is no possibility to add support for the necessary resources to the extension yourself.

Interestingly, the updated F1 only works in the latest beta of Firefox 4 - previous versions of the Mozilla browser do not work with this extension. According to the developers, this situation is due to the uniqueness of Firefox 4, which supports some features that were not in previous versions of the browser.

Unfortunately, there is no possibility to introduce support for additional services into the extension by the user or the developers. Perhaps in future versions of F1, such a function will indeed appear, but so far there is none.
