Every day, several tabs are visible in the history of my browser that I did not open. I checked this several times.

What is it and how to fix it?

It is possible that these pages were opened in a frame on some website as is done quite often. You can sort the history by last visit date to see what pages you opened during that time.

Sure, I have attached a screenshot to the question. There are two sites that appear every day. The second one I did not use several years and the first one I used last month.

What does "a frame on some website" mean?

A website can embed content from other website like a advertisement or a YouTube video.
When third-party content is embedded this way in an iframe then you can still see these pages listed in the history although you aren't visiting them directly.
