I’ve been a little hesitant about installing greasemonkey as I already have too many installed extensions (seven at that time). Even though celebrities (also called A-list bloggers) like Robert Scoble were praising it. What convinced me was this little script that always switches gmail into https mode. So simple, yet so useful. I just could not resist.
// ==UserScript==
// @name GMailSecure
// @namespace http://diveintogreasemonkey.org/download/
// @description force GMail to use secure connection
// @include http://gmail.google.com/*
// ==/UserScript==
window.location.href=window.location.href.replace(/^http:/, 'https:');
And then came the madness of installing more and more user scripts. I was hooked.
