Between clients for the PC and Mac and functionality on mobile devices, Amazon's got no shortage of methods for helping users get content onto their Kindles. Just in case you still weren't happy with the available options, however, the mega-retailer has extended the list to include a Send-to-Kindle Chrome extension that lets users send posts, stories and various other content to their e-readers. The extension lets users preview content and limited it to selected text, as well. Amazon's also promising similar functionality for Firefox and Safari "soon."
