Helping people with computers... one answer at a time.
I'm running Windows XP on a Dell Inspiron 6000. Firefox is my browser. Every time I turn Foxfire on, my screen resolution drops from 32 bit to 8 bit.
If I leave Foxfire on and reset the resolution to the original 32 bit, it stays there unless I turn FF off and then on again when the problem reasserts itself again.
Any idea why, or what to do to prevent it?
Well, I know how to do it on purpose, but having happen by accident is a new one to me.
Let's look at how it's done on purpose, and see if undoing that helps you.
Windows provides this functionality for compatibility purposes. It's not used often, but some old, or perhaps poorly written programs simply can't handle rich color depth.
Right click on the shortcut you're using to start Firefox (or whatever program you're interested in), and click on Properties. In the resulting dialog box click on the Compatibility tab, and you should see something much like this:
As you can see, there are several options that you can select relating to the environment that this particular program would be run under when it's started. One of which is "Run in 256 colors".
I'm guessing that's selected, either for the shortcut you use to start Firefox, or for Firefox itself. Double check both, make sure that option is not selected, and see if that doesn't help.
If it was selected, the question is why? As you can see, the setting is fairly well buried. I'm not certain how it could get set accidentally.
