I used to be able to use Mozilla Fire Fox as my browser with very little problems, but in the past 3 months it's gotten very bad. Every time I log into my Yahoo mail the browser starts slowing down and any web pages I'm on start to slow down and then lock up. Sometimes I have to restart my computer, but that only fixes it for a short while. I even downloaded the new version of Fire Fox, but that didn't help. It even locked up once when I was typing this message to you. I've already cleared cookies, cache and history and that didn't help either. Please tell me what to do to fix this or I will have to start using a different web browser.

Thanks, Mark Nesser
