I get 8.44 bits (1 in 347.34 browsers). I use Firefox with Arkenfox user.js applied on top, with some of my own custom overrides.
However, I think the biggest factor could be because I have Ublock Origin set to medium-hard mode (block 1st party scripts, 3rd party scripts and 3rd party iframes by default on all websites), so the lack of JavaScript heavily affects what non-whitelisted websites can track. I did whitelist 1st-party scripts on the main domain for this test (coveryourtracks.eff.org), but all the ‘tracker’ site redirects stay off the whitelist.
I actually had to allow Ublock Origin to temporarily visit the tracker sites for the test to properly finish–otherwise it gives me a big warning that I’m about to visit a domain on the filter list.
Agreed, and one particular example I can think of is Terraria’s Steam Workshop tools. If I try and publish a texture pack using the Linux-native version of the game, it crashes, but when I use the Windows version of the game via Proton, it works just fine. Not sure if the developers have gotten around to fixing this yet.
Edit: Now that I think of it, it’s a similar story with Half-Life 2 now that they added Steam Workshop support for its 20th anniversary. Crashes on native, works fine under Proton.
