It's regrettable that this is current state. Google equates a login and recent activity with them as being a "legit person". Anything short of that means you're a malicious bot. The traffic dominance of Cloudflare and Google deserves some real independent scrutiny.
Being asked to install arbitrary code to run in browser extension privileged context is perhaps one of the only things they could have done worse than google's captcha.
I'm getting the same thing (residential IP on a major home ISP, no weird VPN or Tor exit node / SMTP relay / any reason to have poor IP reputation). I have recently logged in to Google, so it's not that. I checked the console and noticed a warning about a cross-site request to a 3rd party Google attempting to set a cookie and that this behavior would be dropped in future versions of Chrome. I wonder if this is uBO blocking 3rd party cookies.
Same here. Firefox (RFP enabled) + ublock origin + VPN + Cookie autodelete (so no google cookies) and no captcha. I suspect it's mostly based on IP reputation.
I'm not logged in to google (I only logged in to google on chrome and use firefox for personal browsing) but I do have Privacy Pass extension installed. I haven't see cloudflare captcha for a long time ever since I installed Privacy Pass.
