No videos on any platform will play when I try to open them in Firefox. They are forever stuck on the thumbnail image of the video, and nothing happens when I hit play. I've had this happen a couple times and was able to resolve before by installing updates and uninstalling my Mozilla VPN, but this time nothing has worked. I've tried pretty much every solution I could find online: * Updating Firefox * Updating my computer * Running in Incognito * Running in troubleshooting mode * Allowing autoplay * Disabling hardware acceleration * Disabling addons * Clearing cache and data * Enabling/disabling DRM content * Installing Windows Media Pack I'm running Windows 10, and videos seem to work fine in Edge, if that makes any difference.
