Thankfully only a small fraction of website does JA3/JA4 fingerprinting. Some do more advanced stuff like correlating headers to the fingerprint. We have been able to get away without doing much in Caido for a long time but I am working on an OSS rust based equivalent. Neat trick, you can use the fingerprint of our competitor (Burp Suite) since it is whitelisted for the security folks to do their job. Only time you will not hear me complain about checkbox security.
