I cannot log into Facebook with my Firefox browser. Even though the username and password are entered correctly, the login freezes and I cannot proceed. I am able to access the site on other devices. On my laptop, I deleted all cookies, history, and cache as recommended. I am able to log in to Instagram on this device. Coincidental to this problem: when I try to view video on newyorktimes.com, the browser freezes. I cannot view content in other open tabs and must reboot the browser.
