Excluding extension features, what's your favorite Firefox feature. I think that for me, it's the spell checker. I'm actually learning to spell thanks to Firefox. That's just wonderful. I think that tabbed browsing is probably the Firefox feature I'd next most regret not having.
What feature do you wish that Firefox had built in, and for this one you can include extension features. For me, it'd probably be some form of adblocker, a text area resizer, or a simple language translation tool.
And finally, what popular feature, either in Firefox or available as an extension, would you like to see removed from or never included in Firefox. For me, I think that would be a toss-up between "most of Page Info" and the "Error Console" that I'd like removed.
