Maybe you could attach a screenshot to this message, to show what you are seeing?

Or since you have a number of plugins, maybe you could try starting Firefox in safe mode to see if it still happens? https://support.mozilla.org/en-US/kb/Safe Mode

Thanks, Michelle

I have read your response and appreciate your interest in my problem, however the way that I have resolved the issue that I was having with Foxfire is to uninstall version 10 and reinstall version 3.6. If you have version 10 installed you might encounter the same problem that I was having by going to Craigslist.com and once there go to Pittsburgh, PA. When you are at the Pittsburgh listing go to motorcycles and attempt to look for just the Harley Davidson motorcycles. When I did that I cannot enter Harley Davidson in the space provided. Regardless what I attempt to enter in that space I cannot enter anything. After I reinstalled the version 3.6 version I can enter a search criteria with no problem. To me that indicates that there has been some change incorporated into version 10 that is creating the problem. I would have incorporated an image of what I am encountering but as I said earlier I have rid myself of the problem by reinstalling version 3.6.

davek4 -- I went to Craigslist and have no problem searching for the item you listed. Please see attached jpg. Maybe you can delete your cookies and cache to see if that help.

PS: I am using FF 10.0 with Windows XP SP3.

I have downloaded version twice and when installed I have applied the changes that were suggested. Neither time was my problem resolved. I am now back using version 3.6 and am fully connected and operational. I did not mention in my original request for help that I am operating with Windows 7 and don't know if that makes any difference or not. Thanks for trying to resolve my problem and for now I will either use Internet Explorer of Firefox v3.6.
