Opera delivers the first desktop browser with built-in crypto wallet access – Labs version [blogs.opera.com]

We’re excited to share that we are now releasing the first Labs version of our Opera desktop browser (Mac, Linux or Windows) which lets you seamlessly interact with Ethereum Dapps and Web 3.0 without the need to install extensions or setup a new wallet

Looks like there were some earlier Opera announcements for their mobile browser incorporating a wallet. This is the announcement for the desktop browser wallet.

Personally I think a crypto wallet should be as far away from your browser or other software as possible. It's just too risky to have something like this built into a browser.
