As far as I’m aware WS is pretty close to what you get by just using virtalbox (with an easier setup) so you could do that on Linux. With Linux you also have more advanced solutions though like https://en.wikipedia.org/wiki/Qubes_OS

Write to your country’s anti-trust body if you feel Google is unilaterally going after the open web with WEI (content below taken from HN thread https://news.ycombinator.com/item?id=36880390).

Google has proposed a new Web Environment Integrity standard, outlined here: https://github.com/RupertBenWiser/Web-Environment-Integrity/blob/main/explainer.md

This standard would allow Google applications to block users who are not using Google products like Chrome or Android, and encourages other web developers to do the same, with the goal of eliminating ad blockers and competing web browsers.

Google has already begun implementing this in their browser here: https://github.com/chromium/chromium/commit/6f47a22906b2899412e79a2727355efa9cc8f5bd

Basic facts:

    Google is a developer of popular websites such as google.com and youtube.com (currently the two most popular websites in the world according to SimilarWeb)
    Google is the developer of the most popular browser in the world, Chrome, with around 65% of market share. Most other popular browsers are based on Chromium, also developed primarily by Google.
    Google is the developer of the most popular mobile operating system in the world, Android, with around 70% of market share.

Currently, Google’s websites can be viewed on any web-standards-compliant browser on a device made by any manufacturer. This WEI proposal would allow Google websites to reject users that are not running a Google-approved browser on a Google-approved device. For example, Google could require that Youtube or Google Search can only be viewed using an official Android app or the Chrome browser, thereby noncompetitively locking consumers into using Google products while providing no benefit to those consumers.

Google is also primarily an ad company, with the majority of its revenue coming from ads. Google’s business model is challenged by browsers that do not show ads the way Google intends. This proposal would encourage any web developer using Google’s ad services to reject users that are not running a verified Google-approved version of Chrome, to ensure ads are viewed the way the advertiser wishes. This is not a hypothetical hidden agenda, it is explicitly stated in the proposal:

“Users like visiting websites that are expensive to create and maintain, but they often want or need to do it without paying directly. These websites fund themselves with ads, but the advertisers can only afford to pay for humans to see the ads, rather than robots. This creates a need for human users to prove to websites that they’re human, sometimes through tasks like challenges or logins.”

The proposed solution here is to allow web developers to reject any user that cannot prove they have viewed Google-served ads with their own human eyes.

It is essential to combat this proposal now, while it is still in an early stage. Once this is rolled out into Chrome and deployed around the world, it will be extremely difficult to rollback. It may be impossible to prevent this proposal if Google is allowed to continue owning the entire stack of website, browser, operating system, and hardware.

Thank you for your consideration of this important issue.

They got MS Edge like vertical tabs

To be fair, vertical tabs has been possible in Firefox for way longer than Edge has even existed. For example this add-on is more than a decade old.

One way to hide it for Firefox users.

How do you know that no one who has played PoE has needed/wanted offline mode?

Personally I don’t play PoE because of their policy on respeccing. An offline mode would likely make it possible for me to bypass that with mods.

Speaking of mods D2 had awesome ones so it’s sad 3, 4 & PoE are so locked down with the online mode to prevent this.
