After upgrading to Firefox 7 my browser is nearly non functional. CPU goes to 60% and sticks there

I regularly have about 8 tabs open. When I open the browser it can not load all of the tabs. Some load and some do not. Indeed my memory usage is low, but my cpu runs up to 60% and just lives there. I would appreciate a fix or a link to the old firefox 6 that actually worked. Thanks


In an effort to fix this I have:Installed the new version over the top of the old version:Removed the old version and totally reinstalled (left user profile)
