Hello Steve.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

Yes, I am having this exact problem... I realize it may be the new "skins" thing, but I don't see where to update that add-on... as a matter of fact, that add'on isn't even listed in my tools/add-on menue. I have started mozilla/firefox in safe mode, then I tried deleting mozilla from my programs list... still, when reinstall, same thing happens. if I can't fix this, i'll have to go back it IE, which I would rather not do.
