All the common browsers "potentially" work (Chrome, Firefox, IE, Safari), but not all browsers are configured the same way, since there are innumerable ways that users can customize and configure cookies, privacy settings, etc.. And some people use browser extensions like script blockers and ad blockers, etc, or may be using high security in IE, etc. Firefox might work for one person, but not for another. Chrome might work for someone, but not for another. It's unpredictable, and trial and error. That's why simply changing browsers often works, since it's likely that the second browser is not configured exactly the same way as the first browser.
