How to BLOCK systemtimezone detection in Firefox?

more options

How to BLOCK systemtimezone detection in Firefox? Can this be done with firefox or with the operatingsystem itself? After all i know for a fact that the bromite android browser has this feature and it works. I noticed that disabling javascript blocks systemtimedetection, but it also basically renders the browsers useless for my purposes.. are there specific javascript config settings regarding systemtimezone detection? I really feel that when a website spys on my systemtimezone this is a breach of privacy as this goes beyond the browsers im using to view the website but instead directly access information about my system, im not ok with that... Using a virtualmachine just to fake systemtimezone cannot be the solution, this is ridiculous.

By the way, i hope Mozilla won't let down support for Manivest v2 ever, there is a chance firefox will gain a boost in users after google pushing Manivest v3 that hard... making adblock useless, what a shame.

privacy.resistFingerprinting option fakes the timezone, and much more (but don't be suprised when it causes problems).

I'm already using privacy.resistFingerprinting and have not noticed any issues. What i did notice, even with privacy.resistFingerprinting some websites know my real browser configurations. My goal is to avoid mass surveillance and data collection by big-tech.

I think privacy.resistFingerprinting might be useful but there are techniques that are superior to it. For example this website https://coveryourtracks.eff.org/ always claims that i have a unique (new) fingerprint whenever i visit it. However i can provide two websites where both of them will always with a 100% identify my exact browser, meaning i have the same (old) fingerprint all the time. I set firefox to delete all cookies and history when closed and yet these two websites know it's me when i next visit them, even with a new IP and after restarting the browser. That's terryfing...

So for these websites i'm not a new visitor everytime but a known one who has been seen before, basically if these websites can do this then ofcourse sites like google, facebook, amazon, etc, can do the same. I'm afraid im being profile-tracked on basically any website i visit, they know my fingerprint/hash-sum, they know it's me, and that's exactly what im trying to avoid...

Total Cookie Protection partitions third-party cookies and that should prevent websites from tracking you as they do not have access to cookies they created on other websites, so maybe you shouldn't concentrate that much on seeing those tracking cookies.

Would you mind checking out the two links i provided and let me know your results? I'm just curious if these websites also remember your browser identity/profile even if you have a good privacy configuration.
