Edit: I found the culprit: I had webgl.disabled set to true in about:config. Re-enabling it, then deleting cookies for annas-archive and ddos-guard.net, makes Anna’s search page open without any captchas. Once you reach the search or search-results page, you can set webgl.disabled back to true; subsequent searches seem to work fine (probably a cookie has been stored regarding the pass check).

(Apologies if this isn’t the right community. Given the nature of the website, it seemed relevant.)

I navigate to Anna’s Archive main page via Firefox (no VPN). It displays correctly, but if I do a search I’m redirected to an hCaptcha “I am human” challenge. I solve it, but I’m redirected to the same “I am human” page. Again and again.

I’ve even disabled Enhanced Tracking Protection on Firefox, disabled uBlock Origin, allowed session cookies, and cleaned cookies and cache to start over. Same problem.

Anyone else experiencing this? I start wondering whether there’s something wrong at the moment with hCaptcha itself…
