Get More Productive with Firefox

You already love the Firefox Web browser for its tabbed windows, cool extensions, and other spiffy features. Now learn how to be more productive with it, courtesy of PC World's 15 undocumented Firefox tips. The article includes keyboard shortcuts, Web-search tweaks, security tips, and optimization tricks that promise to improve Firefox's performance. I'm a huge fan of keyboard shortcuts, so here's a sampling from that section:

To enter a URL or search criterion into the address bar, press either <Ctrl>-L or <Alt>-D. If you just entered a domain name into the address bar, don't bother adding ".com"; instead, press <Ctrl>-<Enter> to insert that suffix and go to the page. For ".org," use <Ctrl>-<Shift>-<Enter>; for ".net," <Shift>-<Enter>.
