It's very annoying when I click on a link and it opens a new browser, even
though I already have a browser opened. Even when the open browser isn't my
preferred browser, since it's already loaded, I rather have it handle links I
open from pidgin and whatnot.

I made a patch on sensible-browser that takes that into consideration. As it is,
there is no way to disable its behaviour. If you think it would be best that
this is a configurable option, just say so. I'm willing to fix the patch until
it's in an acceptable state.

Cheers,
Rafael
