Firefox desktop for Windows 10 stopped letting me copy text with the mouse. Copy is greyed out 90% of the time. I really have gotten used to using the mouse to do this. Are they going to fix it? I will have to use a different browser if no fix is in the pipeline. That is how often I use it. Thanks

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
