privacytests.org VS activity-stream

No, https://privacytests.org/ is misleading, it shows only the results of the default browser settings - which absolutely nobody uses.

So as far as hardened chromium forks go brave is the best and all there really is. For Firefox based hardened browsers unless you feel like manually hardened stock FF yourself, librewolf and mullvad browser (mull on Android) which leads me to Tor but with the drawbacks that make it less practical for certaint things mullvad known for their VPN that is is very bignin privacy so much you have nothing that ties to it like 99% of anything now days as yoi have anonimity bcnyoinoau with cash-crypro-or use a voucher no name email address phone number bank etc to sign upso they partner with then tor project and made a clearnet version of tor hardened fingerprint resistant as well as cookies scripts ect multiple identity proxy and built-in security that tor has standard safer safest with no script uBo and and their VPN and dns to take the place of tors multiple relay and encryption that is the tor network with no telemetry you hide in plain site as all the other using it look like you. You can n use this browsers like you would brave or your "main' so history bookmarks passwords etc but that defeats the purpose IMO but librewolf is also very hardened fingerprint resistant focused but you can use it like were using brave and still have the privacy and security and convenience. I use all 4 with different search engines depending on what I'm looking for or doing and of in have to use chrome then ungoogled Chromium on desktop and cromite on Android (fork of bromite which lost support from the devs) mull brave and cromite on is what in use on mobile. This isn't a complete list as FOSS for mobile has quite a few to try these are my favorite, Firefox focus on Android is Worth mentioning too. Sorry for the incoherent book. https://privacytests.org/

you mean https://privacytests.org ?

librewolf https://privacytests.org/ for ios/android brave all the way https://privacytests.org/ios, https://privacytests.org/android

careful with brave https://www.ghacks.net/2023/10/18/brave-is-installing-vpn-services-without-user-consent/?amp https://github.com/brave/brave-browser/issues/33726 among other things like the most popular browser compare site being owned by brave employees https://privacytests.org/ i guess when they say privacy they mean it, keeping things private from you too

https://privacytests.org/ he eventually disclosed his employer in the back area of that website somewhere so thats better i guess.

another one is how certain settings on brave search always reverts back on. or just one the send analytics one. if you use search on a different browser not their own. and etc.

and firefox is funded in large part by google.. do you really think they dont share information?

honestly acting like your browser is superior because no tracking is so silly lol. just use whatever browser you want and tune settings to your liking. harden if you must and move on. is it that much of a hassel? would you rather pay subscription for no tracking?

This site is constantly updated, so there is no need to have the same question all the time. https://privacytests.org/

Something to get you started : privacytests.org

Stock Firefox has trackers built into every last part of it. For example, have you ever click on one of the shortcuts on the default new tab? The details of that click is sent off to Mozilla's servers.

Also, even things as simple as interacting with your new tab is collected and sent to Mozilla's servers.

Being FOSS doesn't make it trust worthy. For example, the firefox home tab is entirely open source, but it will report tons of metrics, which are all opt-out, not opt-in.

You also say that FF uses this data for "features that do not serve the user in any meaningful way." I argue this isn't true - all data sent back is used for your security to update your blocklists, for your convenience to pre-load websites, or for Mozilla to know how to continue developing the browser (which is the most straight-forward to disable). They (say that they) don't use any of the data for monetary gain: ** Mozilla never shares data with any third party.** (this is also the source you linked in the OP).
