There is a weird glitch on top of my browser window. Just bought a macbook pro 2018.
its kinda impossible to make a screenshot but I do have a video of it. Its small bar, first pink now also green flickering on very small on the top of the window.

Can you try posting it on YouTube?
Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
