Rated 3 out of 5 stars
I see a lot of complaints from people claiming that their favorite website stopped working after installing this add-on.
They just don't realize why on the first place did they install this extension? That's because this extension protects your privacy trying to advise connections to unencrypted sites.
If some website doesn't work, ideas probably because it's incorrectly configured (easily hackable), and this extension is trying to protect you by preventing Firefox from sending your data across an unencrypted connection.
People, don't be stupid: don't blame this add-on; blame the sites administrators who should be taking care of their sites security configuration.
