Extension broken?

[dcelasun]

I'm on Firefox, using old reddit and a Pushshift API key. For the past couple of weeks (I think) I can't restore deleted comments or posts. This is what I see when I click "Show original" or "Show author" on a post:

I tried with both the userscript and the extension, same result.

I'm also experiencing issues on Firefox. When I click the "show original" button the orange box to put the API key in never appears. It just loads indefinitely. But it works fine on Chrome still.
