Several sites (FAFSA, Turbotax) say they don't support browser, but list Firefox as supported.

I'm using a MacBook Air with OS 10.15.7, and I've updated Firefox several times. It tells me it's running version 86. However, when I try to access certain websites like Turbotax or even a reader app, it tells me my browser is unsupported. These sites always list Firefox as a supported browser under a list of: try these browsers instead. If I click on the Firefox link they give me, it takes me to the Firefox download page. I've even tried uninstalling Firefox and re-installing it. No luck. Anyone out there have a solution?

Are you using content blocking extensions or possibly Private Browsing mode as that might be causing this problem ?

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

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