It took more than 3 hours but.. I think I kinda got it to work.

Reblog Yourself is back in the Extension Gallery (yes, you need to download it again because it’s a different extension.) It is in beta, and probably unstable, so I’m not sure if it will work, or for how long it will work before Tumblr blocks it again.

For all the people who’ve been supportive today, thank you for your patience.
