Version 2.9 of TwitterBar for Firefox was made available on Mozilla Add-ons today, and it has a very cool new feature: you can now use TwitterBar with more than one Twitter account.
To post to a specific account, just type your message like this:
I am posting to my other account. –@other_account –post
If you haven’t yet authorized TwitterBar for @other_account, you’ll be walked through the authorization process.
If you’ve authorized more than one account, and you don’t specify which account you want to post to, you’ll be given a list of choices:
You can manage your accounts from the TwitterBar options (just type “–options”).
Finally, to authorize a new account without posting to it, just type “–account” in the URL bar.
To install this new version of TwitterBar, download it from Mozilla Add-ons.
The next obvious step is the ability to post to multiple accounts simultaneously, and the next version of TwitterBar will offer than feature. If you’d like to beta-test that update, e-mail me and let me know.
