How does it affect your privacy? Search engines are something different than search suggestions. Your screenshot is about the latter, and you're not locked to use only google.

You can test it on our website too. It's a feature of a website.

What data told the search box on Firefox that I was reading a medical article? My issue is the browser's search box is suggesting that I use PubMed search for my next search. Are you saying the website I'm currently on is making the browser present that suggestion in the Firefox search bar?

You are correct that on this website it's showing use Firefox "Mozilla Support" specific search next time... Is that some sort of Meta tag that Firefox now supports to where people programming websites can affect something the browser presents in the search box... If so, can I disable it?

I don't want the search box changing it's answers because of the webpage I have open in the background. I'm normally typing in the search box to go to a new page or lookup something new... I don't want a website changing what I see in that box.
