Black bar behind the tabs since Firefox 35 update. What could be causing this?

When Firefox is in restore mode, there's a black bar that runs under the tab(s). If I maximize Firefox, it goes away. This started happening when updating from 34 to 35. It really stands out and bugs me, as I tend to use Firefox when it's NOT maximized. Any help would be greatly appreciated!! Thanks!

What computer system and Firefox are you using?

If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drive drivers

Hello, and thank you for your repsonse. Flash seems to be working fine.

Firefox 35 & Windows 7 Home Premium 64-bit.

The only thing I have discovered is that it goes away by using the stock Windows 7 theme, instead of the custom theme I was using. I am going to try the update for my graphics card now and see if that does anything. Thanks again!

If you still have issues, contact the creator of the theme.
