I disabled ublock which is the only other sort of tracking blocker I have and it still gives me that error with no screenshot

disable all extensions but improvetube and try again does this https://jsfiddle.net/rasz_pl/8tkdxL0q/ show same message in lower right corner?

Disabling every extension but improvetube still gives me the same error. Yes, it says "40:1 ReferenceError: ClipboardItem is not defined"

What browser are you using exactly? Full version please :) https://caniuse.com/clipboard suggests you might be using 3 year old browser.

Firefox 126.0.1 (64-bit)

duh I read the date wrong, ClipboardItem will be supported in FF starting, and Im not joking, tomorrow on 2024-06-11 I cant find a way of pasting image into clipboard under FF. Perhaps ImprovedTube.storage.player_screenshot_save_as == 'clipboard' should be disabled if FF is detected.

@junvm enter save as in extension search bar (top of popup), it will find "save as" option set to clipboard, switch it to File instead.
