World of Warcraft, split between a vanilla private server and official Classic. I have a character on each with over 150 days of playtime (although significant chunks of that are leaving the game open while doing other things, and also programming addons while otherwise afk at the bank).
Essentially yes. Basically, think of two JS sandboxes that can manipulate the same DOM. One can make requests, but cannot retrieve local layout data. The other can get layout data, but not make requests. Both can set layout data.
Web developers can use the former 99% of the time, and the latter for more precise work.
You don't have to kill much functionality at all. Scripts that need to access that data should simply live in a sandbox with no network access. They can still do full computational layout.
Yeah, they can very easily get all of that right now. But functionally there's no good reason for any browser to let them. Page layout should be a one-way operation that doesn't allow information back through.
Some of the test sites don't differentiate between random and unique. They may see a randomized fingerprint as a plausible unique user, but it may be different the next time you visit. Other sites may detect that your browser has taken steps to randomize your fingerprint, and use that as an identifying piece of information on its own (power user vs average joe)
Fonts, codecs, hardware, OS, extensions are all parts of a computer that never ever need to be transmitted to a website for it to function. Any information about them should be sandboxed, and if the website wants to display differently based on them, it can send static data or code in and get nothing back out.
If you want to pay attention to the story, it's more or less mandatory to play solo.
Large swaths of the main story are basically a visual novel, interspersed with 4-player dungeons that are easily queued for or completed with NPCs. They have remastered the early dungeons to use an updated friendly NPC AI that makes it a very viable way to complete the game.
