Multiple vulnerabilities have basically obsoleted TLS_RSA, CBC and QUIC implementations.
February 9, 2019:
"Seven researchers from all over the world found --yet again-- another way to break RSA PKCS#1 v1.5, the most common RSA configuration used to encrypt TLS connections nowadays. Besides TLS, this new Bleichenbacher attack also works against Google's new QUIC encryption protocol as well."
Feburary 8 2019:
"Craig Young, a computer security researcher for Tripwire's Vulnerability and Exposure Research Team, found vulnerabilities in SSL 3.0's successor, TLS 1.2, that allow for attacks akin to POODLE due to TLS 1.2's continued support for a long-outdated cryptographic method: cipher block-chaining (CBC). The flaws allow man-in-the-middle (MitM) attacks on a user's encrypted Web and VPN sessions."
Answer #1 below explains how to disable some these by command line, however unpractical it is to do so. Part of the answer involves browser developers making cipher selection far more accessible to your average user; for example, make them as accessible as cookie settings.
