Perfect. This is possibly one of the most innovative features in Froyo! And thanks to you I can use it with my fav browser.

One Request: Right now, if I login using credentials 'A' for Send-To-Phone (STP)... and then later, I go to Gmail and login with credentials 'B', STP stops sending the links, since the credentials have changed. Can you please add a feature that the login I use for STP is independent of the login that I use in the browser. The reason is I use one account for my browser as standard and another account for Android phone. Basically, can STP store the credentials independent of whats there in the Browser cookie? Thanks.

This review is for a previous version of the add-on (0.9). 

Suggestion Appreciated

Thanks for the suggestion, this functionality is in the chrometophone roadmap however will not be implemented for the foreseeable future.
We currently use the browser for authentication as it is the most secure method, however going forward chrometophone will move to oAuth authentication and hopefully at that stage multiple logons will be allowed.
Google are also looking at allowing multiple logins to the same service in the one browser. ( http://www.theregister.co.uk/2010/07/14/google_multiple_account_signin/ )
