Well Firefox doesn't have "wallpaper" but a persona will let you make a simple change to how to Interface looks.

Dear Tylerdowner, your reply to my question was very helpful. Thank you so much.

I'm still trying to learn this persona thing, among other things, and am having a hard time. when I open firefox, there is a corner of the background that says to customize wallpaper (like the corner to a piece of paper folded over) and I click on it and pick a picture and click on "ok" but nothing happens...what do I do? got the toolbar pic done but cant seem to do this part.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Are you using the default Firefox theme (Tools > Add-ons > Appearance/Themes)?

They are now using 'theme' for what used to be a persona to style the toolbar area and use 'complete theme' to refer to themes that affect the full browser.

well I thought I was using firefox defaults.. i am not computer literate and i dont even understand what you mean by screenshot....? i guess i will stop trying.
