Réiteach roghnaithe

This is how I fixed the problem: - I removed and then reinstalled the video driver but the issue still persisted. - I found this link that reset "about:config" : https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings - After restarting the browser I went "about:config" and reanabled "media.mediasource.webm.enabled;true" - somehow the issue was fixed
