AES is easier to decrypt with quantum computers, but a 256-bit key (AES-256) is still as reliable as an 128-bit key on classical computers, which is generally accepted as secure as of this writing (2016).
You can disable AES-128 and other ciphers in Mozilla Firefox, leaving all secure connections to be made with AES-256.
about:configin your location bar; press enter
aes_256in it, and false otherwise
For reasons explained on the Firefox page, you want to disable ciphers which might be preferred ahead of the more secure, AES-256-based ciphers.
You want to add
--args --cipher-suite-blacklist=0x2B,0x2F,0xA9,0xA8 to your Chrome startup command line arguments.
Help plz... I don't know how to disable different encryption ciphers on Chrome.Tell me on GitHub Issues
