Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

I followed the above instructions but still have the same problem as described by the OP.

To clarify, none of the links work in the "Editors Picks" section of the MSN homepage as well as cycling articles directly above it. They do however all work in IE.

Please help, I really don't want to have to use IE.

Well, I didn't have to follow your advice but this morning the problem is solved. I suspect the problem ocurred due to a change on Microsoft's side. Maybe an attempt to get people to drop FireFox and drop down to Internet Explorer. Thanks for the assistance anyway. Bye.
