Browsers in this review run the gamut in cipher support. Firefox (v.3.12) has the strongest first cipher showing (TLS, ECC, AES, 256-bit key) followed by Opera (v.9.63). Firefox also has strong defaults, and 34 total ciphers to choose from. (Click each browser name to view its entire cipher order.)
Opera is impressive because it offers 256-bit symmetric ciphers for the first five suggestions (TLS, RSA, AES being the first). However, Opera doesn't offer ECC support at all, which means that Chrome (v1.0) and Internet Explorer (v.8 beta 2), which do offer ECC, could easily be considered tied for second in cipher support if more than first cipher offered were considered.
Both Chrome and Internet Explorer offer TLS, RSA, AES with a 128-bit key first and with a 256-bit key second. In both cases, ECC isn't offered until fifth. Still, Safari runs away with last place with weak first offerings (TLS, RSA, RC4, 128-bit key is offered first and second), frequent MD5 offerings, and no support for ECC, AES, or 256-bit keys.
