It may be an issue of an incorrect 'sending' of the MIME-type from the site I'm trying to download from. Kind of like when like when you used to click on a binary to download and FF tried to draw it - ending up with a page of gibberish text.

I guess what I'm trying to figure out is how to add an association to a filetype. i.e. if you look in the Tools, Options, Downloads section. Under Filetypes it shows already existing ones and their assiciated action. I'd like to add some there. TTLO used allow me to do that by creating a MIME-type but I don't think it's under development anymore.

Again, it all boils down to: when I click on a '.cab' file to download. The 'save' confirmation box pops-up with a default action of Open. I can select the save to disk radio button but can't set it to default. It's just a minor (turning into a major) annoyance.

I hope I'm making sense.
