Rated 5 out of 5 stars

Great addon. Thanks for the fix - I installed this (from https://addons.mozilla.org/firefox/downloads/file/277984/perspectives-4.5.2-fx+sm.xpi) on v.32.0.3 and it does its job.

The only negative I see is that the addon produces a dire warning on sites with self-signed certificates : "Suspected attack:...".
This is a too severe judgement call, most of the time false, that will stop many site visitors.
I would like to see a more technically correct warning: "Warning: self-signed certificate found. To verify that the site is legitimate, check certificate's fingerprint."

The same for an expired cert: "Warning: expired certificate found. To verify that the site is legitimate, check certificate's fingerprint."

If the user is a bit technical (as I would expect from users using this addon), the proposed warning gives them all the info they need.
If she is not overly technical, you drive her immediately away, following the footsteps of the industry who would want to continue and support the money making business of CA who are satisfied with only verifying the requestor domain's e-mail address.

This review is for a previous version of the add-on (4.5.2.1-signed).
