There have been reports of Google's new reCAPTCHA v3 requiring more image selection in Firefox than in Chrome, but there are no definitive information.
Do you have any privacy extensions installed or the "privacy.resistFingerprinting" about:config pref enabled? privacy.resistFingerprinting is known to cause problems with reCAPTCHA v3:
Yep. One ungracious explanation could be that Google is penalising Firefox users, but a more likely reason is that Firefox successfully blocks some of the information leakage from the browser that Google uses to decide whether a browser user is a bot or a human. I’ve no doubt that Chrome is very secure, but I do doubt that Google does much to stop it sending data back to Google controlled domains.
Well, Chrome comes from Google, so if you don’t trust Google to store your data I’d recommend not using the browser at all. I certainly don’t (apart from for unlogged-in development testing), but if you do then there shouldn’t be a problem.
I certainly don't trust Google, and I don't use any Google products. But that's a bit beside the point.
What I was trying to get at is that if data is being sent from a product to the manufacturer without your knowledge and consent, then that is a data breach no matter how trustworthy the collector of the data is. Such products cannot reasonably be called "very secure" in a blanket way.
Saying something like "very secure against outside attackers" would be more correct as, to use the Chrome example, Google is an inside attacker.
Anyone else finding this?
