If you encounter a web page in another language, now you can use Siri's built-in translator to turn it into one of seven languages. Plus, Safari now shows favicons in the tabs, so it's much easier to find the tab you're hunting for.
If you're like me and have dozens of tabs open at any given time, you'll like that you can now hover over a tab to see a preview of what's there. Apple says Big Sur brings the 'biggest update to Safari since its original launch in 2003.' It's speedier than ever (50 percent faster than Chrome, according to Apple), and you can finally watch 4K HDR content on YouTube and Netflix.
