can't login to my wifi router or if it dodoes it's prone to freezing up

'''More info please.''' What router? Maybe someone out there has the same. What OS? What version of Firefox? Do you have the same issue with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf Did you try clearing the browser cache? https://support.mozilla.org/en-US/kb/how-clear-firefox-cache# i can access my linksys with no issue. What happens in another browser? Can you show us what you're seeing when you try to access your router?
