This question is for using webmail (spamcop email, in a browser).

Whenever I receive a message in HTML format, I have to click to open a new window in order to read it. While this functionality is probably for security, and probably something many people want, it is for me a slightly irritating extra step (and takes more time, sometimes).

Can I turn this feature off, so that HTML is rendered as soon as I click on the message? Or, can it be turned of for people who're in my address book (currently noone, but that can be changed)?

I searched this forum, and looked at the FAQ, and didn't see an answer about this.

I do not believe that is an option at this time.

You may want to check out http://www.horde.org/imp/ (the application being used) to see if that is an option or an improvement being worked on. You may be able to request that feature there as well.
