Mark Twain knew what's up

That's the guy from that TNG episode!

To quote the great Mahatma Gandhi: "Yes"

Sounds like an OPSEC disaster waiting to happen.
Seems to be a security feature that is bypassed by a Chrome feature.
Go to about:config - find option browser.tabs.closeWindowWithLastTab - set to false. If you're only using the close tab button, it will never close out of the program. If you're closing a lot of windows using the window control though that won't really help.

What about Safari? Why no one ever talked about it?

It's the only browser (that I know of) that allows Netflix streaming in 4k.

I'd assume because the majority of people here don't use Apple products
That's only because you use a Mac, on Windows only Edge allows 4k Netflix. It's the integrated browsers that have the HDCP hardware features so it allows 4K
- Could that be achieved with "Chrome on Windows" spoofing on FF?

Chrome is the pimp Firefox is the whore. Vanilla Firefox is full of spyware from Google.

Absolutely not, and there are other forks like Waterfox and Librewolf which are very much focussed on providing custom versions of FF, focused on privacy, security and freedom.
- Yes, this forks are better than Vanilla Firefox but I'm not referring to them in this case
  Other point, Firefox is not so secure as you think
How do you figure? Firefox is not a chromium based browser, and Mozilla is not owned by google.
- Yes, Firefox is not based on Chromium but that doesn't exempt it from being full of built-in Google crap

All I know is he really loved including the N-word in his books.

Of all the shit you could call Mark Twain out on, treatment of African Americans isn't one of them. His books humanized them, despite his upbringing in a community where it was ordained by the church and state, and his father owning several as well. As he grew older, those views became more and more apparent.
He's required reading material in a lot of Critical Race Theory courses.

Wait - are you saying people didn't have our modern social norms back then? Who would have thought!
