On the topic of crazy firefoxes, I've collected a nice suite of Firefox addons for 3.6 that maximize screen space, speed of use, and add some good functions. Check out these if interested:
Download Statusbar
Enter Selects - faster Awesomebar usage
Fire Gestures - Mouse Gestures!
Hide GUI Bars - Hides all the tool bars; toggleable/atuomatic
OpenDownload - Gives the option to "Run" a download like in IE
Smart Stop/Reload - Combines the Stop and Reload button, since you don't need them at the same time
Tab Mix Plus - Better Tab control/ progress bars
Toggle Menubar - Used in conjunction with Hide GUI Bars so pressing alt only brings up the menu bar (instead of all bars)
Adblock Plus
Greasemonkey - Used for making specific sites more screen space efficient
NEW Glasser by SzymekPL - Aero eyecandy!
Disabled, but kept for utility:
DOM Inspector
DownThemAll!
Firebug
Stuff I tried at one point and is good, but doesn't go w/ my current setup:
Fission
foxiFrame basic
Locationbar2
Stack Style Tabs (now I use the built in one)
