Hello,

Since this morning when I open a web page, there’s a black rectangle that appears at the top of my screen and at the bottom across the entire width for 1 second, then everything goes back to normal.

Maybe someone can inform me about this problem?

Thank you in advance.

    hello

    check the complementary modules of firefox/disable them....
    and re-enable them gradually.

    or reset firefox.

    eventually, if windows is up to date, you update your software
    with update checker?
