Website won't load in Firefox

[MWTaft]

I'm using FF on a mac. The Duolingo website will not display properly. It's just a blank white page except for the "Support" tab on the side. Nothing else.
Any suggestions (besides switching to Chrome)?

Do you have https everywhere installed?

[MWTaft]

yes

Try disabling it. That extension seems to be causing problems for now.

[MWTaft]

Yep, that fixed it. Thanks!
Please let me know when I can re-enable it.
