Streaming: when I go fullscreen, it leaves the taskbar at the bottom.

Hello,

1- If you are using a browser like Firefox or Chrome (you already have it), check the taskbar options.
Like this:
Right-click on the taskbar → Taskbar settings


2- The graphics card.
Check that the driver for your graphics card is up to date, as this manages the videos.
Go to My Drivers
Or download My_Drivers_3.0.4.exe
Check → Show only drivers newer than the installed ones
Check → Show only WHQL certified drivers
Uncheck → Also show beta drivers
Click on → Validate.

See if you have a driver to update.
Look for the green highlight, it will indicate a new version.
If you have one, download and install it.
It will uninstall your old driver version to install the new one.

3- Try the Netflix app from the Windows store, since you have W10.
It's on this page


4- Restart Windows Explorer when you're on Netflix.
Ctrl, Alt, and Delete → Open the Task Manager.
File (top left) → Run a new task
Type → explorer.exe

5- Keyboard key → F11
Press F11 again to exit.

6- It's not very important, clear the cache of your browsers.
Here's the tutorial.

Ps:
Can you tell me what the icons on the taskbar correspond to?
- Green circles with 3 lines. (can't remember).
- Ghost head icon that looks like Scream :-)
- The yellow shield next to the clock.

For IDM, disable it from Startup.
Open IDM, go to Download then Options.
General tab.
Uncheck the first line.

For the cloud icon, it's OneDrive.
You have the Task Manager to help you disable this in the Startup tab, but that's not what you asked for; anyway, it will save you some boot time on the PC.
Check or compare.
