Twitzer is a Firefox plug-in which lets users post tweets longer than 140 characters.

Features:

• Firefox plug-in overlays Twitter.com to shorten tweets over 140 characters
• right-click to execute tweet shortening
• link to entire tweet by shortxt.com

The Good:

Twitzer is another of the tweet-shortening apps out there, and it does a good job. Successive releases have added features and fixed wee bugs. When viewing with Firefox, all of the work is done right within the Twitter site.

The Not-so-Good:

While the tweet shortening to less than 140 characters works well, Twitzer (like other such apps) will cut off your tweet right in the middle of a word and then provide the link. It is really a stylistic complaint, and not a serious one at that. Of course, Twitzer only works with Firefox, but we view that as a positive thing.
