Always on top, that's what this addon lacks isn't it, but it's mozilla who has been preventing addons from controlling windows, but we're not out of options, see below how to use "Always on top".
Instead of creating my own software to work together with the addon, I decided to use Microsoft PowerToys, which already have this function, I believe that everyone will trust it, right?
To keep it simple I'll just leave the Microsoft Powertoys link, follow Microsoft's instructions to get it working.
