When I browse to https://meta.codereview.stackexchange.com/https://codereview.meta.stackexchange.com/ using Firefox, I get a message that the security certificate is bad because it's for *.stackexchange.com and *.meta.stackexchange.com (among others). I have to add an exception in order to view the meta site.
replaced https://meta.codereview.stackexchange.com/ with https://codereview.meta.stackexchange.com/
