If you are a Firefox user, you probably already know that you can open links in a new tab by right-clicking on the link and selecting the "Open Link in New Tab" option. While this is nice, it is sort of annoying since you have to click once, navigate to the correct entry in the menu, then click again. Turns out there is a way to open links in a new tab using a single click.

Just click on the link using the center button on your mouse. This obviously only works if you have a three button mouse. For most modern mice, clicking the scroll wheel acts like clicking the third button. Give it a try, you'll be surprised how much quicker this is!
