Just out of no where I was having problems with Foxfire locking up, particularly in programs like Gmail. I heard there were problems with certain versions so I clicked on Help in Foxfire to see which version I had. In the Help drop down, it showed that I had only partially downloaded an updated version. I tried to complete the download, but that didn't work, so I went to the Mozilla Foxfire site and downloaded the latest version, 3.6.13. After I downloaded the latest version, everything is working great again. Note that when you get into the setup/installation of the new Foxfire, if it says you must close Foxfire and you think it is already closed, type Crt-Alt-Del to get to Task Manager. Click on the Process tab, find foxfire.exe in the list, click on it, and then press End Process. This will allow the setup/installation to proceed. Good luck.
