Happens to me, too. Not all the time, though. I’ve assumed it was just some glitch due to running XP and a thoroughly outdated Firefox. Keep meaning to change browsers, but never do.
On general principles you ought to download Brave and ditch Guugle anyway.
I finally got locked out of most of my websites (except FR) for running Windows 7. I can’t imagine XP working with much of anything online now.
After a small level of chaos and adventure I’m on a new laptop running W11. Meh.
