I made Bing my browser and it was working fine until today. When I open Firefox I get a message Ref A: and then a long string of characters. I click on the home icon and the string changes. After doing this several times I get the Bing search page. I do not get the Firefox start page with the tool bar that has my book marks, history etc. I cannot clear the cache if I cannot not get the history tab. If I go the the mozilla firefox program folder and open it, there is a tool bar but cannot clear recent history, etc. there. I do not have an administrator & password on my home desk top; it is just me. I tried to follow your suggestions, but they do not apply to my situation. I really don't know if this is a firefox or bing problem. I used google before bing and had no problems; just wanted to try bing.
