Activating this add-on effectively locked me out of my facebook account. When I went to log in within the container it said my password was wrong and to change it. I did, using my email account to enter the code proving it was me. Then, because I have two-factor authentication, it required another code via the app on my phone. I do not have facebook on my phone. Therefore I cannot authenticate. So I DL'd FB on my phone and obviously can't log in there because my password was changed. I requested a text authentication code for my phone number that it registered to FB. Never received a text....so now I can no longer log in to facebook at all. Absolutely infuriating. The only other option is to submit a request to facebook with a photo of my ID. Not happening. I guess this really is a facebook container after all. Facebook is in the container and I'm out of it.
