Amazon has officially released its Send to Kindle for Mozilla Firefox today. Customers can now add the Send to Kindle button to their Mozilla Firefox browser and quickly send news articles, blog posts, and other web content to their Kindle. They can then read web content anytime, anywhere on Kindle devices and reading apps.
You can send content to one or more Kindle devices and Kindle reading apps, or you can simply archive it in your Kindle library to re-download later. With Whispersync, your last page read along with bookmarks, notes, and highlights are automatically synchronized across your Kindle devices and Kindle reading apps (with the exception of PDFs).
A few months ago, the company officially released its Send to Kindle for Google Chrome extension and will be releasing one for Safari in the coming weeks.
