hi, this support forum is staffed by volunteers and other users like you volunteering their time to help. in case you want to troubleshoot an issue you'd first have to describe it in more detail and provide some relevant information about your system/firefox configuration for us to be able to provide effective help. if you want to do so, please open a new question... in case you just want to leave feedback about the browser, please do so at https://input.mozilla.org/feedback instead!
