Here i will be writing my ideas on Google Chrome web browser extensions:

- Warn/disallow non SSL access
people concerned not to send their passwords in plain text over internet may like chrome extension which warns user if user submit password type web form on a HTTP only (not HTTPS) page. Firefox has addon https://addons.mozilla.org/firefox/addon/snap-http-padlocks/ and it shows tooltip when i click into login form field on HTTP only page.
