They removed the Experimental tag. It is a full browser now, and has a built-in reader mode.

Tried it, and you are right about experimental being gone. I tried signing into google and got a message about browser doesn't support Javascript. Gave up.

You can turn JS on or off from settings, but IMO having limited support is a feature. The average site would wreck havoc on a Kindle's processor and battery life if it could run all scripts normally.

I got there just by searching directly and it works. I wish the reader mode had an option to make it work like a book though, web scrolling is a nightmare on this thing.

I dunno. My advice to new owners of a ebook device has always been to put it in airplane mode the second it comes out of the box. Get all the ebooks you want to read from LibGen or Anna’s Archive and sideload them over USB.
