Firefox login crash

Hi Paul,

I am unable to paste the first line of Socorro so I unloaded a screenshot of the crash page. The problem began with my phone running very slow; using up most of memory. I ran my virus scanner several times…nothing has come up. The programs affected are Firefox and YouTube. After two days of troubleshooting YouTube is loading properly. Firefox is still slow. The crash occurs when I try to log into my Yahoo account. I can view the Yahoo webpage but cannot login to the account.
