Fingerprinting works by collecting bits of information about the browser and device to identify users. Couldn't browsers like Firefox see when a website gets such info with JS and either prevent or ask permission from the user for the website to make HTTP requests to upload such information to the website. Idk if they do something like this already.

If anyone wants to check, here is a video showing a Firefox dev. console (F12 key) and errors occured on https://www.openstreetmap.org/search?query=Oslo#map=8/59.973/10.723

I would like to find the causing extension without the need of disabling extensions randomly or by disabling half of extensions, then if issue solved, disable half of that half etc..

Sometimes it helps to hover over the link near the error on dev. console (F12 key), Console tab, to see the moz-extension://somestring and find first characters of the string at page about:debugging#/runtime/this-firefox Though this time, it does not show that IMO (per the linked video).

If I should click something particular in a FF dev. console (F12), please guide me. Thank you.

I did the tests on fingerprint.com/demo/ and https://coveryourtracks.eff.org/ and they both said I have a unique fingerprint, even when I enabled privacy.resistFingerprinting to True.

I read the descriptions for the Dcentraleyes and LocalCDN addons which cache popular JS frameworks and page assets to enhance privacy and speed up pages that use them (since the assets were downloaded beforehand). Does Firefox have any built-in functionality to cache frequently used assets, or are there any addons that do so?

For instance, If I access Reddit.com a lot, I would want all the resources that all those Reddit pages have in common to be cached automatically to make loading pages from the domain faster.
