I run Linux, use my own VPN, and use Firefox with uMatrix. CAPTCHAs are one of the most user-hostile things I experience on the web. I've had to give up on registering for sites, or signing into sites I'm already registered with, because after literally minutes I still hadn't gotten through. I actively try to avoid sites that use CAPTCHA but unfortunately it's not always possible.
Had the same setup &, i found that on brave i can do them in 20 secs compared to 3 minutes. Not saying I support them messing with FF but at the end of the day, I need to get things done.
