Firefox slows down when I use web developer tools, I use this whenever I try to save an image on Instagram or other sites that I go to just to save an image or look for the video using the web tools.

Is there a way to fix this issue it lags the browser or it freezes for a second.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
