When using Waterfox and I am trying to stream video content through my HDMI port to a Vizio TV, I encounter a variety of issues. 1) The audio content comes across but no video (black screen) (The most common issue) 2) I can sometimes get the connection to work by starting the stream then plugging in the HDMI connector rather than connecting with the stream paused. 3) Twice, I crashed Windows (Win7) by unplugging and plugging the HDMI cable in while trying to get the thing to work. That is not something I would want to risk again unless some possible bug is found and removed first. All extensions were disabled and I was updated to the latest Waterfox version. The sites I can't use are PBS Passport and The Smithsonian Channel for sure, but I never tried YouTube out of fear of creating another system crash. I tried moving to Waterfox because I liked the speed and many of the features, but I had used Slimjet (64 bit) for years and have never had this HDMI interface problem.
