You don’t want them to save the order of your bookmarks? why
I’m actually very happy to see your comment as it means Lemmy might actually not just be full of tech nerds, because it’s clear you have no idea what you’re talking about or don’t know how to properly communicate your issue.
Firefox isn’t tracking your bookmarks and selling it to advertisers, Firefox is open source. They keep your bookmark order as convenience so that you can have them in the order you like. Same goes for history, it’s just a tool to see what sites you’ve visited if you’re trying to get back to one, it’s not tracking you.
