Nice article ! I would like to share some tips to watch online videos when you have slow internet connection .
Choose lower video quality settings (such as 240p and 360p) from the gear icon in the bottom right side of the video player.
Start the video and then click the Pause button immediately. Wait for the gray video progress bar to load a bit before clicking Play.
Change your video player settings to not default to the highest quality stream.
Try watching a shorter video; the shorter the video, the less time it takes to load.
