not working for me.

Why does the extension requires access to twitter.com ?

It works, but there's an unexplained new permission in the latest version. It needs to "Access your data for sites in the twitter.com domain" which seems unnecessary.

Edit: I looked in the source code for the extension ("Debug Add-ons" in Firefox) and couldn't find any mention of Twitter.com there.
Either this was included accidentally, or it's for future planned features. Either way, I don't think it belongs in this extension.
Edit 2: removed extension.

Doesn't work. I click the button and it shows "Displaying 0 saved threads."
