Hello, I was using the Web Developer Add-on > https://addons.mozilla.org/en-US/firefox/addon/web-developer/

I was using it on one of the HackThisSite (HackThisSite.org) problems.

I discovered that it wouldn't let me Copy or Paste any of my HTML to complete one of my objectives.

Below is a screenshot of me trying to paste my code:

Use keyboard shortcuts if the buttons on the web page or other methods aren't working.

  • Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
  • Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
  • Cut: Ctrl+X or Shift+Delete (Mac: Command + X)

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.
