Personally, I usually use Chrome for the majority of my web browsing. Being LearnKey’s webmaster though, I need to at least have a copy of the major browsers around to test things, and I recently installed an update to Firefox 5. Our graphic designer Kari pointed out a pretty cool and useful feature Firefox recently added to their updates – Tab Groups.
Say you’re working on a few different projects at once, and you don’t want to mix up the different tabs you have open between projects. You could open a new browser window and separate them that way, but Firefox’s Tab Groups feature lets you keep it all in one window, and switch between groups easily. It’s fairly similar to the Spaces feature in Mac OS X.
