Yes, but the company says it shares data “conservatively” and Firefox is known for being a less data-hungry provider than some other browsers. Is Mozilla sharing my data with advertisers? If you type in “iPhone,” Firefox pulls relevant searches from your enabled search engines (it’ll default to Google) and will suggest other search queries like “iPhone 13” or “iPhone 13 Pro Max.” This is obviously a useful tool to see popular searches related to what you’re typing, but you could shut it off to avoid having your internet experience influenced by everyone else’s search activity. Lastly, having “Search engines” enabled will show suggested keywords in your search. There’s no set threshold, at least not publicly, for determining a “frequently visited” site - but you’ll find out what sites you’re checking out daily if you have this enabled. If you usually open up Instagram as soon as you open Firefox, it’ll suggest doing so as soon as you start typing in the address bar. Having “Shortcuts” enabled will pull up your most frequented sites. This is a good one to have enabled if you’re constantly opening new Twitter tabs even though you’ve already got one open. Under your regular search results, there will be an option to jump over to another tab. With “Open Tabs” enabled, Firefox will let you know if you have a tab open that’s relevant to your search. This can make jumping to bookmarked sites a bit easier if you have a lot of sites saved in complex folder systems. With “Bookmarks” enabled, any websites you have bookmarked will pop up under the address bar if you start to search for them. If you start to type the name of a recipe you remember looking at last week, Firefox will pull that URL into your search results.

With “Browsing history” enabled, Firefox might suggest previous websites you’ve visited based on your search history. These can actually be pretty helpful though - let’s break down each one so you can decide whether or not to keep it enabled. There are two options here that you’ll want to toggle off: “Suggestions from the web” and “Suggestions from sponsors.” Checking off these two boxes will ensure that the search results you see are based on popular search data, not your internet activity or any collected data.Īs you can see, there are a few other ticked boxes above these two settings.“Suggestions from sponsors” is the setting you’ll want to toggle off to nix ads.
