Works well, new proxy and some bugs Rated 4 out of 5 stars

I love it, I've put up another proxy on: singe.za.net ports 8080 & 8443

Some bugs in the add-on in Firefox 3.5.7 on OSX 10.6:
* You can't add a new proxy, information can be entered but clicking 'OK' does nothing.
* The OK/Cancel buttons on the add/edit dialog aren't displayed, the window needs to be resised to see them.
* By default firefox won't let you go to the site as the cert is untrusted. It won't even let you accept the risk. You need to either go to https://proxy.googlesharing.net/ and accept the cert there, or view it and export it to add as an authority. The second seems more risky but I'm not sure why the first method works just yet. Some solid advice on this would be useful.

This review is for a previous version of the add-on (0.12).
