This all started while I was trying to open Spotify in Firefox. It kept telling me I need to enable secure playback. So I checked and "Play DRM-controlled content" is enabled. I did some googling to see what could be the problem. Turns out I need Google Widevine enabled, so I check the plugins page where I find out I don't even have Widevine installed. I also checked the default profile folder (root directory) to see if there's even a gmp-widevinecdm folder there but I couldn't find anything.

Is there a way for me to reinstall Widevine without having to create a new profile?
