Spend Tor Browser to as many people as possible instead of work until everyone uses it and gchq/nsa cant monitor anything. Recommend on linux. In China tor blocked google "tor circumvention"

tor (TBB) doesn't work for everything and most people want something fast and convinient that only takes clicking a few buttons to get working. They will think it is too much work.

I recommend Brave browser which can use tor in private browsing mode but also has a regular browser with encrypted DNS (cloudflare, https strict, and shields) for things like banking, shopping, and online accounts (that might help to have a password manager for).

Also, Tor browser does not have any passthrough for security keys but Brave based on chromium does. Tor browser does not have a password manager.

Firejail should work on a profile for Brave as sandboxing is always helpful. TBB can be sandboxed easily, however.

This "multi-tiered" approach would be better for most people who aren't just accessing a handful of onionsites that replace or are in opposition to an entirely different set of services than those usually accessed on the conventional internet (online banking, social media, a few publication sites, and a search engine).
