YouTube and home banking screen goes black and then returns to normal after a few seconds

[fabiodanzetta]

Hi everyone,

Something strange happened to me yesterday and today:
Yesterday, once I logged into my home banking site, the screen suddenly went black, even the mouse pointer was invisible, and after a few seconds everything returned to normal and the site was visible again.
Today, the same thing happened while I was watching a music video on YouTube.
As for home banking, I didn't use Safe Money, but in general, I installed the Chrome extension and set it to block data collection and banners.

Thank you all.
