Space Bar will at random, stop working. I have tried Troubleshoot mode and works. then a day or two space bar stops working. I uninstalled and reinstalled and have the same issue. This does not happen on Edge, or Google. If I am doing online work, I don't use Firefox because of Space Bar issue. Please advise.

Does this happen with all sites or only some? Can you give an example site?

Try disabling your extensions.

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
