For some websites will be displayed at login or request captchas. After updating Firefox to 62.0.3 these captcha will not be displayed anymore. That was still the case with the older version. I do not use any addons like adblocker etc, have cookies and cache cleared, Firefox cleaned up and even uninstalled and reinstalled Firefox. Always the same problem. No captchas are displayed. I can not log in or make a request. What's wrong?

That second screenshot is a red flag, cause that shows that you have malware : "Update-your-PC. info" is a browser hijacker.

See : https://info.greatis.com/howto/remove-update-your-pc-info.htm

As you don't have any other extensions installed than the two that we already "covered", I will not ask you to look for any suspicous or unfamilar looking extensions.

But I will ask you to run all malware scans that are listed in this article :

Re you first screenshot - would you please take a look at this article :

Hello McCoy, Great, Fantastic, Thank you a thousand times for your help. No more malware anymore (both screenshots will not be displayed anymore) Even the captchas will be displayed again. I think both were related. I just can not understand how I got this malware on my system. I have not installed any free software,games etc. on my system in the last weeks - I only updated firefox. Thanks again for your help. Best regards
