Just when I thought I knew it all
I just learned that you can ctrl+click taskbar entries to tile their windows. Go try it now. I’ve found this comes in handy with a widescreen monitor where one giant wide window isn’t as useful as two side-by-side (like stormtrooper footprints) windows. Props to Lifehacker for finding this.
I frequently type the wrong userid in a web form only to have firefox remember it and suggest it when I revisit the page later on. This is particularly annoying when the typo shows up first in the list of suggestions. Little did I know you can just select the misspelled entry and hit delete. No more typo. I will never try and log in as dogu again! [Edit: It looks like LH has covered this one before too, with a very similar post. Those guys are good]
