Hi, from what I can tell you're using Mac OS 10.15 which is a beta version. We are still working on support for their beta version, I believe it may be released in the next Firefox version - 68.0.1 - but until that's released we can't say for sure.

A workaround in the meantime could be to use a Beta version of Firefox (69b3 or later) which I believe already has support for Mac OS 10.15.

Note that using the beta version should create a new separate profile, but changes in one version will not be reflected in the other.
