My Facebook business manager and my entire facebook account got hacked directly after installing this extension, and without resetting or changing my password and that's another proof that it was this extension since it has an access to the cookies, He used the cookies to access my account and removed all the members with full access to employee access then added his fake accounts and posted something that violates Facebobok policies to lead my account to suspension and now he spent over $15,000 from my accounts and credit cards and he still trying to take more, I own a digital marketing agency and I had many clients with large budgets for Ads and he just terminated all this and terminated my whole career and life after I lost all clients and many of them are sueing me now after the large amounts taken from their cards and the large thereshold of their Ad accounts I used to manage, I am speechless for real no words to describe how it feels, I never got hacked before for over 20 years with zero scams or phishing attacks and after all this, a chrome extension terminates my life, Please be careful and I hope no one ever to experience what I been through the last days.
