Amazon is introducing a “Send to Kindle” button for Mozilla Firefox, the company announced on Kindle Help Forum. The add-on is already available for free download here.
Thanks to the button, Firefox users can send content to their Kindle device without leaving their browser. As detailed below, it means that they can save articles to read later or to archive.

The button is compatible with Firefox version 6.0 or higher, and lets you preview content before you send it to your Kindle. You can also choose to only send selected text – for example an interesting section of a long article.
It is worth noting that a similar button was already available for Chrome users. According to Amazon, support for Apple Safari is coming soon.
