I have Hulu live tv streaming and the video is not streaming. I get a black screen when I select a channel or an item from the library. This also happens when I try to stream local tv stations' 24 hr streaming sites. Other streaming services (Disney+, ESPN+, Netflix... etc) stream just fine. Hulu works perfectly in Microsoft Edge but I truly prefer not to use it. I've been using Firefox for years. This has happened after the latest update of Firefox. The update before this latest I experienced a similar problem and using the trouble shoot mode narrowed it down to a problem with Adblocker Ultimate extension. I deleted the extension and reinstalled it and the problem corrected. I did the same this time and no success. I have cleared the cache and reset Firefox and still the problem exists. TIAF any help.
