Thanks for the suggestions. This redirect "hijack" had been occurring, as I said, in both Windows and Linux, in Firefox, Chrome, and Microsoft Edge.
I checked the advanced settings for Privacy | Content, and on each I already had Pop-Ups blocked.
Upon installing UBlock Origin in Firefox and Chrome, I could see it working immediately.
For Microsoft Edge, they have uBlock Origin in
their store.
For Pale Moon, I used
this.
There is a reason I use so many different web browsers.
Yes, Raul, DuckDuckGo, I have used that in the past in Linux.
Again, thanks for the tips.
I have been deeply engrossed in studying, as well as running my mom around to various doctors. I realize why I stay awake late into the night or wake up very early - so as to study in peace.
It's a relief to have this redirect blocked. Maybe I will be more likely to post again now.
Thanks again.
