Gemini pops up on the website and generates text.

As shown in the figure, pop-ups with blue or white text on a blue background often appear on web pages, and Gemini generates text based on words related to the site—this happens frequently on other sites as well. I’m not sure if this is a problem with the website itself, my device, Firefox, or Google’s search engine. If anyone knows how to fix this, please let me know. I’d like to get rid of it if possible. https://yasashiigo.com/glossary/ta_gyou/damezumari.html This is the page shown in the image. I’m using an HP computer, but the same thing happened on my smartphone as well.
