Twitzer is a Firefox extension which lets you post text longer than 140 characters on Twitter.com (Twitter.com has a limitation of posting a maximum text length of 140 characters).
Twitzer - Twitter long text now supports De-Twitzering of text on the Twitter site itself.
If you want to post more than the 140 character limit at Twitter, install this extension. Now type away as much as you want and before posting just click on "Twitzer text".
Twitzer - Twitter long text will automatically save the full text at shortText.com, create a URL and replace the typed text with the summary and URL.
NOTE: The Twitzer - Twitter long text - add-on is cross-platform and it works on Mac OS X, Windows and Linux.
