FWIW, the Steam Hardware Survey says 99.99% of users have SSE2 (under

For that to be valid, one must assume that the population of Firefox
users and Steam users are sufficiently similar. I don't think that's
necessarily true since most Steam titles have substantially higher
system requirements.
The last time we broke this (by accident) was several years ago. At the
time, we got vigorous complaining from various people who had relatively
recent bare-bones machines without SSE2.
It might be worth reconsidering now: I'm not willing to throw away 0.5%
of our users without good cause, but perhaps there is a good cause to be
made here? What would the performance gain be for the remaining 99.5% of
users, realizing that we already have dynamic SSE2/non-SSE switching in
place for some of our hottest paths.
