Requires permissions to access data to all websites but we can't inspect the code. Pinterest's similar extension was removed by Mozilla for its privacy violations. Arena's extension needs more transparency.

I love are.na and this would be a perfect addition but the add on won't accept my login credentials, i just get 'Login failed. Invalid email or password' every time

The bookmarklet was my favorite part of Are.na, and now I can use it with Firefox too. It's a seamless way to save content to your channels. ++

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.
