Leadfoot, it really is easier to use FireFox and it's a much better and a less intrusive browser.
If you give it a try and can't figure it out, I'll personally walk you through it.
Let me give you an idea of it's ease.
1. Download the application by clicking their download box. It will pop up a box that says "save file". Click it.
2. After it downloads, it will put an icon on your desktop (front screen) of your computer.
3. Click it.
4. Check the "I agree" box and hit next.
5. It will install automatically.
6. It will ask if you want FireFox as you main browser. Check "yes".
7. It will probably ask you to restart your computer.
8. Internet Explorer will try one more time to not lose your business and ask if you want to keep IE as your browser. Click no and the "don't ask again" box.
FireFox will also ask you if you want to transfer all of your favorite places/bookmark over to FireFox. Check yes. They will still be in IE if you decide to use IE at a later date.
That's it. It's actually easier than I just explained it.
Now, as you browse the Internet, there will be a little thing that drops down if a site has pop ups, etc. If it's a site you like, like MF, then in the options box click, OK. It won't ask you again after you tell it "this site is ok".
The problem that you are having with signing on has to do with how pop ups and cookies are handled. To sign on to MF, you need to accept cookies and allow MF to use pop ups. It's not to spam you. It's because all of the fancy features here are pop ups. Even the box that you log in with is a pop up, "I think". But I know that all of the drop down choices for your profile, etc, are recognized as pop ups to browsers and if you have a pop up blocker, you are fighting against all of our awesome features here. That is why so many are having trouble.
Here's the Fire Fox link. Just click the download box and you're on your way to ....THE FUTURE, lol. >>
