Hello,

Have you tried disabling all of your extensions by following Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems?

if you have, then in Safe Mode can you try disabling hardware acceleration and see if that changes anything?

1. Click the menu button and select Options.
2. In the Firefox Options (or Preferences) window, click the Advanced tab, then select General.
3. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
4. Close Firefox, wait a few seconds, and start it again normally. Do problems still occur?

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base article:

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Did this fix your problems? Please report back to us!

Thank you.

hello mfoxboyd, 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).
