“looks like Firefox quietly added ads into the address bar”
I must ask those who are still sticking with Firefox over Chromium-based browsers, especially those who do so soley for the purpose of staying off a Google web monopoly, to what end? When and how do you think Mozilla will ever do anything to help the web? They integrate all of Google's non-standards just as quickly as Google does, take Google money, and then do adamantly anti-user stunts like this and the Pocket and the incessant VPN shilling. And it's significantly harder to make a good version of Firefox, you have to mess with userscripts or profiles or LibreWolf or cross your fingers and hope some nebulous omnipotent distro maintainers just take care of it. With chromium there are several builds with the spy and suck stripped out readily available because most of it is blobs or API keys, very easy to just exclude at build time. See https://chromium.woolyss.com. I make this comment partially because this is one of the more egregious things Mozilla has done recently but also because I've recently switched to Chromium myself and the whole experience is much faster and smoother so I recommend everyone do it. Happy to be debunked.
