Mac Mail won't open links in Firefox

[slynger]

I've googled this and everything I find is a few years old. For a while now, when I get a link in an email, that link default opens in Safari and not my default browser of Firefox. Every setting I can see looks to be where it's needed. It used to work and now I'm not sure if they removed something or if I'm missing a setting.

Please help.
