How do YOU use StumbleUpon? And what browser do you use?

I've been *ahem* stumbling around trying to figure out how to use StumbleUpon effectively, and I think my major (dare I say it? Yeah, why not) stumbling block is that I don't like to download toolbars. They slow down my browsers, and I do a great job making my browsers slow with my two bajillion tabs already.

But StumbleUpon really wants us to use the toolbar, huh? I can't seem to figure out how to do anything on the site easily without finding directions that I need to use the toolbar to do what I want to do. Okay, so I give in. I'll download the toolbar, right?

Except that I can't. Because there's not an official toolbar for Safari, which is the browser I mostly use to do my general-purpose browsing. Ahhhh. Yes. Now I remember why I had so much trouble getting into StumbleUpon: because it's not friendly to my chosen browser. Does that mean I have to completely change my browsing habits (not just by adding a new habit, but by literally switching which browser I use most often!) just to start using SU? Yeah, that seems pretty unlikely. Guess that's why I haven't been active on SU.

All I really want to be able to do is start the process of stumbling a page in one click, in the browser I actually use to browse, which tons of other social bookmarking sites will let me do. Sheesh, StumbleUpon. I don't think that's too much to ask. ;)

Am I missing something? Is there a way to do this that I'm too brainless to have noticed? How exactly do you add a stumble a new Web page or site?

And to go back to my original question. For those of you who are way more active on StumbleUpon than I've been: Do you use the SU toolbar? What browser do you use? Do you find the process of stumbling kind of counterintuitive?
