Best web browser in terms of security?

Yes, ETP blocks known fingerprinters with a respective blocklist. But as mentioned, privacy.fingerprintingProtection = true randomizes canvas and fontmetrics fingerprints, so it's another additional approach which is applied also on sites where no 3rd-party fingerprinters are found. I've been using it for many months and it hasn't caused any problems for me contrary to what @Brummelchen said. And just in case it does, it's easy to deactivate ETP on a per-site basis via the shield icon in the address bar.

 

Hi summerheat,
What I meant to say was,
I have Firefox ETP Custom set to block known fingerprinters and suspected fingerprinters in all windows.
I never set privacy.fingerprintingProtection = true in about:config.
Yet in about:config I see the preference is set as privacy.fingerprintingProtection = true.
Therefore, I guess my ETP Custom setting to block known fingerprinters set that preference in about:config (like many other Firefox settings in "Settings" (about:preferences) reflect in preferences in about:config as well).

 

hi
can i ask you have you enabled on linux and android?

 

Hi mantra,
I don't use Android, as yet.
On Kubuntu 24.04, Firefox snap is installed.
In Firefox, Settings, Privacy & Security, Enhanced Tracking Protection, I use the Custom settings.
In ETP Custom, I checked all boxes, including "Known fingerprinters" and "Suspected fingerprinters".
For Cookies, I selected "All cross-site cookies".
For Tracking content, I selected "In all windows".
For Suspected fingerprinters, I selected "In all windows".
The Enhanced Tracking Protection fingerprinters settings reflect as privacy.fingerprintingProtection = true in about:config. I did not edit that preference in about:config.

 

just returning from work with a clue for me
i was wrong, i should have had "privacy.resistFingerprinting" in mind which is causing so much trouble. shi*ame on me.

 

Thank you, Brummelchen.

 

no problem, just a weird old man, sigh.

 

Ah, yes, you're right. If I remember correctly, ETP was available earlier and with a later version they added FFP to ETP strict and custom.

 

On the contrary, ...

... Indeed, it blocks fingerprinters using a block list included the Disconnect block list, but doesn't falsify date like RFP. Edge uses the same Disconnect block list.

 

Thanks, summerheat.
I think that's right.

 

"privacy.fingerprintingProtection" was implemented between firefox 102 and 115.

 

Firefox.

 

Most definitely NOT firefox, not anymore. A fork maybe, but not firefox.

Also, try https://fingerprint.com/demo

You should probably get a different visitor ID each time you visit it.

 

Firefox with UBlock Origin (UBO) and Noscript Security Suite (NSS), one or both extensions as you see fit. Also, remember, no matter how robust and secure your browser is, at the end of the day, somewhere out there in the big shiny cloud, someone, somehow will leak your data.

i count 1x safari, which is not available for windows or linux, its apple only.
7x chromium based, and 4x firefox based.

mullvad is similar to tor - if i need an alternative from firefox, i would chose mullvad. because tor is too special, and librewolf is concerning functionality complete crap.
betterfox is a timebomb, it has unoffcial changes which are not tested against all odds. same for betterbird. the mozilla team is aware of the changes and some of them are on the todo list, but always with care and dozen of tests running. some of them made it, some not.

i dont have doubt that other browsers preserve more the so called "privacy" from their view. nevertheless i dont need a browser which is crippled or broken.
chrome is a disaster if not managed, same for edge. alternative possible for me: vivaldi.
