Okay, this is a weird one. I have been streaming the video feed from a .tv site for several years (I like to chat and discuss episodes with other watchers). Last night, the feed wouldn't load; I thought this may have been some slowness in my internet connection, so I shut my Windows laptop down and went to bed. I got up this morning and logged in, and the feed was doing the same thing (loading bar; three dots cycling over and over). I checked if there were any new updates for Firefox (there were not), and likewise any changes to the Windows codecs (all files are current). The rest of the browser (other open tabs) are working normally. Cleared the cache - same result. The feed was playing normally for the other site viewers, as I could see them commenting on the episodes that were currently playing. I then checked if I could access the .tv site via a different browser (MS Edge...ugh); and the site loaded and played normally. I checked it on my phone's browser; site played like it usually does. Hmmm... I then opened Firefox Private Browsing, typed in the site... and it's playing normally. Still nothing on my usual browser. Any Ideas?
