Firefox started posting a request for donations on the start page. After that I could not get it to browse. The beach ball would spin and end up with the start page and a donation request. Firefox was my browser, but it wouldn't browse. I downloaded the latest version thinking that would help, but after the free download, the opening page was the donation page. I don't know how to make the browser browse. I click on my favorites and nothing, beach ball then homepage with donation request.
