Good, but not works on Instagram.com

Fails at saving ANY "x.com" Tweet page

Internet archive is doing God's work.

This is one of the most important tools on the internet! Never forget it!

Very good, very crucial addon, but after the Wayback Machine came fully back up into service in the wake of the outage, this extension's "Save Page Now" functionality has been spotty. Frequently tells me "Error: you need to be logged in to use 'Save Page Now'", despite the fact I am logged into the extension (and yes I did try logging out and logging back in, and this is after resetting my passwords on my Archive accounts).

EDIT: apparently this is a problem on the server API end, which is being looked into currently.

Essential addon for preserving a free and open internet for future generations!
