annoying certificate errors Rated 2 out of 5 stars

At first, I thought this extension was very good. It allowed me to toggle my +1 status of any page and it showed me the current status for each page after it loaded. The only thing it lacked was the ability to share the page via Google+. Based on those features, I would have given it 4 stars.

However, I've just recently found that this extension makes many annoying certificate error dialog boxes to appear. This happens when I'm connected to a network, but I've not yet authenticated. What I believe is happening is this extension tries to load the +1 button via HTTPS, but the response it gets back is the authentication page for my network, which uses a different certificate. So the error message says that the certificate the extension received for is invalid, because the certificate is for instead. I think to avoid this problem, the extension should be updated to do a non-secure HTTP connection first, to test the network connection. If it fails, as is the case when I've not authenticated yet, it would not attempt to load the actual +1 button, but show an icon that indicates the button couldn't be loaded.

If this certificate problem and the sharing features were addressed, I would give this extension 5 stars.
