Nice feature, needs polish Rated 3 out of 5 stars
I like the basic functionality of the extension but it has several flaws needing fixing before it can become a worthwhile tool. I will follow-up this review by sending the flaw list to their support channel.
o display of tweets in sidebar is organized and useful
o character counter for tweet entry is a nice touch
o no way to hide/remove the Twitbin button on the toolbar
o the first tweet is displayed as soon as it's entered but subsequent tweets are not displayed until one exist and reloads Firefox
o It doesn't afford auto-login so one needs to login each time they open the the browser.
o Opening a new window displays a blank twitbin sidebar without any toolbar buttons. Closing and then reopening the twitbin sidebar seems to fix the problem.
