I have some questions about UBO (uBlock-origin) filters:
A
How can I know (not exactly but at least the average) how much bigger is Adguard filter from EasyList filter from same category. For example:
under “Cookie Notices” or “Annoyances” category, UBO offers two filters: Easylist & Adguard. How much differences/additional rules they have? 1%, 90% ?
B
The “uBlock filters – Cookie Notices” filter exist under both EasyList and Adguard? What is the difference?
C
I have multiple Firefox profiles with arkenfox-js and UBO.
“daily” profile (I always close all tabs and remove all cache and cookies every 5 minutes)
“gmail-1” profile (I don’t delete the cache or cookies)
“facebook-1” profile (I don’t delete the cache or cookies)
Does below filters protect my fingerprint? Does enabling them really worth it?
“AdGuard Tracking Protection”
“Social widgets” (under this category they offer multiple filters)
They are 2 big different lists so very difficult to give you a percentage of difference unless you conduct a stats scientifically.
Even more so if their approach is different too, e.g, EL’s tends to have more generic cosmetic and network filters than Adguard’s. It means EL can potentially cover more sites, but also potentially have more breakages somewhere, and vice versa for Adguard.
uBlock filters – Cookie Notices is the supplementary list for the sites that need trusted filters, aka the filters that have extended capability but not suitable for using widely by default without users’ own settings changing.
By default, trusted filters can only be used within uBO’s internal lists, hence the need for a supplementary cookie list. The common trusted filters using in the cookie lists are trusted-set-cookie/local-storage-item to set complicated cookies / storage items and trusted-click-element to auto-click on cookie button (“reject”, “agree”…).
Fingerprint is better be protected by the browsers than extensions. Enabling more lists could help reduce the number of external connections, but at the same time could also have filters that whitelist the connections unnecessarily.
The Social widgets does have network filters that can block external connections, but in many cases they just block 1st-party connections so they don’t matter very much. The rest are just cosmetic filters to hide elements, they don’t affect data collection any way.
That said, it’s better to learn about uBO’s dynamic rules + no-scripting, so you can switch to default-deny modes instead of enabling more lists
It can break the websites easily tho so read the documentation carefully.
You can simply copy the settings of Mullvad’s browser uBlock-origin. (Export - Import)
They adjust them a bit from the default values as far as i can tell, and you are still getting a generic settings profile for a bit of fingerprinting protection.
