Hi, Firefox 88 is the latest fully tested release. Firefox 89 is in beta testing for several more weeks. I'm pretty sure they don't expect you to install beta software to use their site.

Is Firefox 88 able to use your camera on other sites? Here's a test page example:

Very strange. I use v54 as my default and the clip played for me.

Websites say that Firefox is outdated or incompatible even though it's the latest version

You can check out at the browserspy website how websites see you:

Hello, Everything I checked met the various specifications you gave me so I disabled all the add-ons and extensions and the web site worked perfectly. Thank you for your help. Hayward

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
