Are you using Tor by any chance? That's the only time I got these captchas.

No Tor, no VPN. Nothing too far out of the ordinary.

I usually search in a private tab, enhanced tracking protection set to strict, uBlock with most default filters enabled.

Oh and a "Google Search Fixer" extension because the make the UI much worse for Firefox. Maybe it's one of my extensions, but DDG never traps me in captcha hell.
