I checked out http://us.dlink.com/ and had no problem. Win 7; FF 54 and 58 Check out these links; https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox http://www.howtogeek.com/113439/how-to-change-your-browsers-user-agent-without-installing-any-extensions/ ------------------- Many site issues can be caused by corrupt cookies or cache. * Clear the Cache and * Remove Cookies '''Warning ! !

Thanks for the info. It did not work. Looking at the MyDlink site again , it appears that it supports only a 32 bit OS for Windows. i seem to have a 64 bit OS. Chrome works for me so I have a solution. Can you suggest anything else to get FF to work on a 64 bit system.

Install the 32bit version from; '''[http://www.mozilla.org/en-US/firefox/all/ Download Firefox For All languages And Systems]''' {web link}

Thanks that was helpful

Is the site working now? Good.
