Rated 4 out of 5 stars

Mr. Alertbox author, everyday, I want to receive my alerts by e-mail like I receive the slashdot.org newsletter.

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

Then it wont be an alert, it would be an email containing the summary of changes that would be delivered and many cases may be too late for the user!

Or, maybe you do not wish to have email alerts and instead want to have summary of changes emailed to you. Will keep it in mind when designing future versions.
