Hi, Must be so frustrating .... Assuming that you're talking about 'Grammerly', the add-on - would you please take a look at this article : https://support.mozilla.org/en-US/kb/disable-or-remove-add-ons And as you are on Mac OS : http://macuninstallguides.com/remove-grammarly-1-5-28-on-mac.html Any good ? If not : somebody else is bound to come to your rescue ! May I suggest that you remove your phone number - this is a public forum and you don't want to be inundated with 'weird' phone calls ! Unfortunately we don't provide phone support - Mozilla doesn't have the financial means to run a call center ......
