This is a very capable Firefox add-on that greatly facilitates adding content to the Are.na service. Of particular usefulness is that it will automatically source where your content came from, so you can add image or text blocks to your Are.na channel largely free of guilt that you are somehow in the process obscuring where that content came from. Remember to be a good web citizen and credit original content creators!

When I first wrote this review, I had one minor complaint that it did not let me write the title or description of image blocks that I saved using this extension. This has since been addressed, and it works like a charm. I can open the extension, designate an image that I want to add to are.na, and then customize the title or description of the block prior to submitting it.
