Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode

Thanks for the response jonansuse. Been attempting to deal with this for quite a while. I think it may have to do with a setting. Tried many things but nothing seems to work. Guess I'll just use Safari when it is encountered. Thanks for your effort.

Hi alaskanaturally I think you are using VPN and unfortunalty most of the sites test your connection as they usually see VPN usage from bots, thus you get that "I am not robot" test. I suggest to stop using VPN cuz most of the time it is not so nessosary. You can use it when you actually need it but for normal dayly usage I suggest not to use VPN.

Mirlan, I do not think that is the problem. I'm having it on my Mac not a phone. I do not think that a VPN is on the computer. Thanks for your input.

Can you provide us an example of a site that gives you issues? I use Kaspersky and they use captcha, I get by it with no issues.

The site is a little painful... had to turn off Ghostery, but I was able to create an account and repeatedly login. see screenshot
