Browser still uses TLS_AES_128_GCM_SHA256 (0x1301) 128-bit SSL encryption cipher even when disabled in about:config
Even after disabling all the 128-bit cipher suites in about:config, the cipher TLS_AES_128_GCM_SHA256 (0x1301) is still being used.
I used Qualys SSL Labs Client Test (https://www.ssllabs.com/ssltest/viewMyClient.html), and saw that TLS_AES_128_GCM_SHA256 (0x1301) remains to be the most preferred cipher suite.
All TLS 1.3 connections, such as facebook.com and cloudflare.com, uses that particular AES-128 cipher suite.
Is this a feature or a bug?
