Newly appointed Mozilla CEO Brendan Eich has his share of detractors, but few are more high-profile than massive dating site OkCupid.
The site, which gets 10 million unique visitors a month, is currently greeting all Firefox users with a note explaining why OkCupid's owners feel Eich is "an opponent of equal rights for gay couples."
At issue is a $1,000 donation Eich made to support California's Proposition 8 in 2008. The constitutional amendment successfully banned gay marriage before being ruled unconstitutional in 2010.
OkCupid's roadblock for Firefox users doesn't stop them from visiting the site entirely.
