web address and click Allow Button, ALSO check for any BLOCK settings. Click 

Works on my Win 7 Pro 64 bit system, running FF 3.6.15 I do not recommend bookmarking any financial web sites. Manually type the address carefully is the best security practice. Never store passwords on your system unless they are encrypted with a strong password. Or you are telling the "bad guys" way too much if your system becomes compromised. FF settings: Tools, Options, Privacy Tab, Exception Button, add http://www.frederickcountybank.com web address and click Allow Button, ALSO check for any BLOCK settings. Click close button, ok button and Test the results. Check your security software settings, you may be blocking at that level, firewall and FF add-ons.
