As I was using firefox, I opened one web address in my favorites folder, and suddenly all websites opened up in different tabs. I closed firefox and when I reopened it it asked me to restart in safe mode. When I eventually opened up I wasn't signed in so I attempted to sign in using my email, it stated that was not found so I used my other email to no avail. I then asked firefox to email me my username using both emails. I did not receive any email. I am in limbo, all my add ons are not accessible because I can't sign in. I don't know what to do. I'm not worried about my password, I just can't get my user name straightened out. Please help. Thank you.
