Firepost enables you to quickly and easily:
- Sign in to your App.net (https://join.app.net/) account;
- Make quick postings from within Firefox (small window, shortcut enabled ctrl/cmd+shift+s);
- View App.net user profiles and app.net hastags from the Firefox AwesomeBar (address bar) via an option setting;
- Quickly share postings from other users (posted to your own stream);
- Post to App.net from Twitter's share window;
- Receive notifications when you're mentioned;
- Receive notifications when you're followed.
Note: on OS X notifications require either Growl (http://growl.info/) or Firefox 17 + Mountain Lion. On Windows notifications use the built-in Firefox notification system.
