What version of Firefox? What OS? Post the links here to see if we can replicate the issue. 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

I opened firefox by clicking on the icon then opened my gmail, opened my VA news letter clicked on the link and it opened. That was great! So what do I have to do to make that work by opening it from my windows task bar?
