I just migrated from Win XP to Win 7 and my Firefox and Thunderbird are now a light blue color and Firefox is see through at the top. I would like to be able to change the color. This light blue/white is hard to watch. I'm running FireFox ver. 30 & Thunderrbird ver. 24.6.0.

The appearance of Windows 7 is drastically different than Windows XP. You can try looking in themes for something to make Firefox look more like it did on XP https://addons.mozilla.org/en-US/firefox/complete-themes/
