Firefox won't respond to my keyboard or mouse.
Sometimes when I open a FireFox window the only part of the window that will respond to my mouse or keyboard is the "X" in the upper right to close the window. The page will be fully loaded but I still can't type in the field that it defaults to (my homepage is Gmail so it's the user name field) I have to close the window and open a new one to get any response. Sometimes I have to repeat this two or three times. Does anyone know how to keep this from happening at all?
A few times a week
== I installed the latest version of the software
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 themes and this one for plugins.
If you need support for one of your add-ons, you'll have to contact its author.
If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.
