Copyfish for Firefox stopped working

Error code : “Unable to capture screen. Please try again when the page has loaded.”
Was sent here by developer from https://addons.mozilla.org/en-US/firefox/addon/copyfish-ocr-software/reviews/
Same error as the user and it has been this way for MANY months now… I actually disabled Copyfish since it stopped working but tried 1 more time recently just to see if it had been fixed, but sadly no.

I use Copyfish, too. This is probably an issue with this specific website. Can you post the link to it?

No, its every page that displays same error, no specific website

I have even tried removing all other addons to see if its a conflict but Copyfish still only displays the error message.
Im on Firefox 81.0 64bit
