This comment about my Quick thoughts on Opera vs Firefox prompted me to go and tweak the search engines that Opera supports through fields on its toolbars.It involves a little bit of ini file hacking (easily explained) or you could try this Opera Search.ini Customizer. It works quite well, and Opera supports HTTP:Post search requests. Firefox can’t do that.I’ve still got a couple of things on the next-actions list relating to Firefox so I won’t switch back for a little while at least. Yesterday, Jon Udell again posted about Nic Wolff’s Password Generator. It’s a really neat javascript function that performs an md5 hash against your master password and a website domain to create a unique password for the site. Udell actually did a cool ‘screencast’ a while back which demonstrates it nicely. Anyway, I tried it before but decided it wouldn’t work in Opera.So now I’ve found an extension to this simple single sign-on mechanism, password composer, that uses GreaseMonkey to automate and integrate the process within the site itself. I’ve been meaning to try GreaseMonkey as well so this’ll take care of both.
