here's a counterpart for Chrome if anyone's interested: https://chrome.google.com/webstore/detail/mpbpobfflnpcgagjij...

I just installed it, seems to work as expected. Shows the indicator on both Google and Twitter

really though, just google's servers because google is the only spdy-enabled site where https is forced. twitter doesn't come in over spdy unless you type in https.

Twitter does have an "Always use HTTPS" option for when you're logged in.
