Possible false positive Rated 4 out of 5 stars

Please check https://my.bitdefender.com/dashboard - addon says this site is vulnerable while numerous other online heartbleed test services says it's ok.

Good! Rated 5 out of 5 stars

This is definitely the best add-on for Heartbleed checking, as it does everything locally, sending nothing out (if the version notes are to be believed).

The Privacy Policy needs updating to reflect this.

Works well with good notification pop-up Rated 3 out of 5 stars

Appreciate the privacy policy. I've tried all the available Heartbleed extensions and I like this one the best... nice simple pop-up at the bottom from the status bar.

However the Heartbleed checker you use at http://heartbleed.prod.mozaws.net/bleed/ seems rather slow to respond whereas Filippo Valsorda's own checker at http://bleed-1161785939.us-east-1.elb.amazonaws.com/bleed/ seems to respond instantly. Not really any fault of this extension, just something I noticed.

This review is for a previous version of the add-on (0.1.1-signed).
