FireFox opens but the header is blurry and the body is all black
FireFox opens to my default page, but the header is blurry and the body is all black so I can't see what is on the web page. The status bar is clear and it shows that it opened to my home page, but I can't see anything. I can scroll around the web page and the cursor changes from an arrow to a hand signifying that it recognizes links, but I don't know what the links are since I can't see anything and I can't change anything on the menu bar which is blurry. I tried restoring my computer to a known good restore point, but that didn't fix FireFox. I have a Dell XPS running Windows 7 Pro (x64) with 8GB of RAM.

hello m_k_f, other users with this problem all had an embedded intel hd3000 graphics card with an old driver present. in case this also applies to you, here would be a link to update the driver, which in turn should also address the black firefox problem: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23764 (for win7 64 bit)
in case this doesn't solve the issue or does not apply to your system, start firefox into safemode by pressing the shift key while the application is launching & disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).
