Streamed videos need to buffer every few seconds.

Hi! I have been using Firefox for quite some time, and as of yesterday I have encountered a problem. Any site I try to watch video on, be it Twitch, Youtube, etc., the videos now pause every 1-2 seconds to buffer for 4-5 seconds. The progress bar at the bottom of the Youtube videos will say they are loaded well passed the point its stopping to "buffer" at, and this is only occurring on Firefox, I have tested other browsers and am not encountering this issue. Troubleshoot mode also doesn't change anything, and neither does private browsing.
