ProtonMail encrypts/decrypts messages in the JavaScript client, which is how messages are encrypted without the server ever having access to the plaintext. If you must disable JavaScript, then ProtonMail isn't the mail service for you(unless you use their mobile app).
Another commenter put it aptly when he said something to this effect: "It is [2019]. If you lobotomize your browser, you might find that a lot of the web doesn't work for you."
If you know a JS-free captcha approach that is of similar quality to Recaptcha, I'm sure the Protonmail folks would love to hear about it.
How do you want to decrypt your data client-side without running a software to do just that?
Unsurprisingly, HTML cannot encrypt your data.

I never had to do that.

Applies to pretty much all websites that use captcha. The purpose of captcha is to stop spammers; just suck it up or switch browsers.

Why would you want to do that?
