I created an account in myReach when I downloaded the app onto my iPad. I used Apple ID. I would like to use the extension in Firefox on a pc. How do I log in to the extension?
We haven’t yet developed the Login for Google and Apple ID for the Plugin extension, it’s in the works 
In the meantime, if you open a Firefox browser page and login to myReach, it will log you in automatically in the extension as well.
Hope this helps! Let us know if it still doesn’t work for you
