Spelling issues

How do I get rid of those annoying red underlines while I'm typing or quoting someone?
Basically, whenever I'm writing, my words keep getting flagged with that red spellcheck line. How do I make that go away?

Thanks in advance...

If you happen to be using Firefox:
Tools -> Options -> Advanced -> General -> just uncheck "Check my spelling as I type"

That’s it. Thanks a ton.🙏

Honestly, that red underline at the Metropolitan Opera was driving me absolutely crazy—it actually helped me out too.
