truly revolutionary

thank you so much for this!!
i have a small request though, could you add css classes to the popup's elements so it's easier to style them using custom CSS?
thank you :3

love ya

greatest of all time ty

not all heros wear capes

This is a good extension to have! Thank you.

Just thinking, is it possible to have the pop-ups appear on the right side of the website? I have extensions that make that side underutilised and it would be great to be able to move the pop-up position there. I've tried mucking with the CSS a little bit, but I couldn't figure out how to change the position of the pop-up after it initially appears.

very cool!

If the script isn't working for you, replace every mention of "twitter.com" with "x.com", including the API calls.
