Almost 100% of the time, when I move the Firefox window left or right, the content stays fixed on my screen -- using Windows 7 Ultimate -- how do I fix so that
How do I fix it so that the content moves WITH the frame as it is moved left or right. Works O.K. in the up or down direction. If the frame has been moved to the right, leaving the content fixed, the "buttons" do not work until the frame is manually moved back to the left side of the screen. I am using Windows 7 Ultimate (x64 bit) with a 1920 x 1200 LCD display in the PORTRAIT orientation, and Firefox version 13.0.1. I do not have this problem with Internet Explorer or Chrome.

Hmmm, could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
orange Firefox button or classic Tools menu > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
If you restart Firefox, is the issue resolved?

Thank you very much. This (disabling graphics hardware acceleration) solved the problem. For reference, I have an EVGA GeForce GTX 590 graphics card and twin Xeon CPU's.
