Assuming you aren't using a VPN, something on your PC or other device on your network could be sending unwanted traffic. Scan for malware, keep software updated and reduce the number of devices connected to the network to a minimum.

I'm using a vpn, the windows defender didn't find any malware and I'm at the newest version of windows, how ever I did once tried to fetch images from google while forgetting to add a delay. This was like 2 months ago and I got this problem for 2 weeks now.

This is common for IP addresses associated with VPNs. Captchas aren't all bad since they indicate your browser is harder to track.

Yes but it is VERY annoying, which means I guess I will have to move to a different browser. I suspect there is something I will have to buy from Mozilla to keep this from happening. It does not just pick on one IP address. It picks on my actual IP address and I can tell you that I am NOT being malicious online but it also picks on the IPs for my VPN. Is Mozilla really unable to provide this service without have to make us jump through the Captcha hoop on a fairly regular basis. I won't be back to see if anyone responded. Guess I am going back to Duck Duck Go. They were not bad. Maybe they care.

No, this problem is between you and Google. If you prefer using DuckDuckGo, you can change your default search engine to DDG: Change your default search settings in Firefox.
