Firefox access to websites hang on cloudfare service

Your system info shows you're using some "privacy protecting" addon like CCleaner's Kamo that confuses major sites to the extent they might not even serve you any response. Please try with these protections disabled if you see any improvement.

Thank you for the suggestion. I turned off the only extension and still have the issue. It is only when I use the FF clear site cookies and turn off FF enhanced tracking, I get access to a website that is blocked by Cloudfare and get the Recaptcha puzzle to show. This is primarily a FF issue. Please see the screenshot. Even though the Yahoo homepage shows no trackers, turning off the features shown grant access to blocked websites and allow the Recaptcha puzzle to show. Thank you.

Can you go to https://www.whatsmybrowser.org/ and post here the shortlink they give you in the blue header? Thanks.

The problem still seems to be with FF blocking sites especially sites using Cloudfare. Also, FF also is crashing lately.

There seems to be something messing with your secure connection headers then, if it's not an addon. If you're using AVG, Avast or similar and use some of their "privacy" or "anti-fingerprinting" features, you might need to reach out to their support how to proceed.

Your fingerprint is definitely out of the ordinary, stands out more, and changes between requests, which looks dubious — and doesn't come from Firefox, some of your other appliances must have been adding it to the connection. These random additions shouldn't be there:

Thank you for the reply. I have uninstalled AVG products multiple times and FF blocks the same websites. I used to be able to clear the cookies and turn off enhanced tracking in the FF is on guard icon and it usually solved the problem but not lately.

Could you please elaborate or point to a web explanation of your statement: "Your fingerprint is definitely out of the ordinary, stands out more, and changes between requests, which looks dubious — and doesn't come from Firefox, some of your other appliances must have been adding it to the connection. These random additions shouldn't be there:"

The fingerprint changes hourly per settings so I am not sure of the changes between requests. The "other appliances" is not understood. Please explain.

Thank you.
