Taskbar annoying when watching full screen?

Hello So when youtube / netflix look at the pc, the taskbar does not go away, if I put the video on full screen, yes you can hide in the desktop mode (not always with the mouse on it) but that must go differently because before I have my pc back law I went it (taskbar right and firefox) because the task bar on the right then the full screen knob locked because it is completely over it and synonymous a part of the videos it annoying extrem stop Thank you in advance

This is probably due to your PC may be that your mother loves

You can right-click on the bar and then fix or not
