viki.com stopped working and won't play videos anymore when accessing website from librewolf

Viki.com stopped working a few days ago, When i go to the site it says the browser isn't supported and gives me a list of browsers to choose from. Firefox is on the list, if i ignore the warning and try to play a video, I get this message.

"oh no, it’s not you — it’s your browser. (Error: VF_VJS_1001) Unfortunately your browser is not compatible with this content.We suggest updating your browser or switching to another browser.?"

I've been using librewolf as my only browser for more than an year now and never had this issue before with viki. I thought it might be a drm plugin issue but netflix works just fine.
