Firefox down

I opened up my Firefox today after a week away and have not been able to connect to anything. I’ve tried other browsers and they function fine. I’ve emptied the cache of cookies, uninstalled, reinstalled, restarted my laptop but for some reason, despite it all, Firefox is the one that refuses to work. Even now I’m getting ‘Secure Connection Failed’ and I’ve been at it for three hours at this point. Do i just need to take my laptop into store at this point?
