In the last few days, a transparent rectangular panel is showing up in the upper right hand corner when I open certain websites--Washington Post, The Nation, and Talking Points Memo, and this morning Kanopy and the Zojirushi website. It often covers functions like login and search. I can *see* the buttons, but I can't click them through the transparent panel.

Hi

Do you have any add-ons installed in Firefox?

Are you using content blocking extensions?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.

I have Facebook container, group speed dial, OneTab, and Ghostery.

Ghostery is a content blocking extensions that can block data and might be causing to hide some content and leave a transparent block behind.

You can 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 "Refresh Firefox" in the Troubleshoot Mode start window
