If you're not a fan of relying on browser add-ons and plug-ins, you'll probably want to enable a feature that can help you ditch at least one of them. Firefox now has a built-in PDF reader, and while it doesn't offer all of the same features that Adobe's version does, it's more than sufficient for most uses.

Amazon has updated its OS X app with some new features readers should find useful.

First up, Amazon's new 1.10.3 version of Kindle comes with support for more OS X gestures, including panning and swiping. The app now supports Amazon's Kindle Format 8 books, which deliver some improved formatting options.

Amazon scored some headlines last week after announcing an updated line of Kindle Fire tablets, including the Kindle Fire HD, offering an 8.9-inch screen and 4G LTE service. Amazon also offered up the Kindle Paperwhite, an e-reader that comes with backlighting.

Amazon's updated Mac app is available now in the Mac App Store.
