Uncaught exception?

In Firefox, I'm not longer able to capture screenshots. The error popup says "Uncaught exception" and something else but it goes away too quickly to read the rest.

I've updated Firefox, reinstalled the extension and restarted the browser without success.


  • Which method did you use?

    Did you try the other ones and do they work?

    I get the same "Uncaught exception" error when I choose "Select area" or "Visible page".

    If I choose "Select element", I get this message:

    These particular pages cannot be captured due to Chrome's security policy, please try another page!

    Note: Restarting the browser or reinstalling the extension might fix this.

  • Can you try grabing a screenshot from a different webpage, ex. google.com

  • Google.com seems to work. Other websites like ESPN.com, Facebook.com, etc aren't working.

  • hmm i was able to get that too work also.

    Strange. I just tried it in private browsing and it works fine so I don't think it's another extension that's affecting it.

    And it was working perfectly the other day.
