I'm using Windows on this laptop, this seems to affect all sites with any sort of Cloudflare protection, including Cloudflare's support and discourse sites, pubs.acs.org, and annoyingly some sites necessary for my current projects, that I need to access daily.

To clarify, this is the "Verifying your connection is secure" captcha before the site is even displayed, not a reCAPTCHA after the site is loaded.

I've tried clean browser profiles with no difference, on my normal profile I just use uBlock, Tree Style Tabs (FF)/Tabs Outliner (Chrome), and Tampermonkey for some sites (but not the ones affected by the captcha loop, in this case).
