Firefox opens but nothing shows/load in the window, not even menu buttons

Question

I open Firefox & a window opens but nothing loads or shows up, not even menu buttons. Occasionally when you blindly click around some menus will open but options beyond that don't produce anything.
I have (not necessarily in this order):
Uninstalled Firefox, deleted all remaining folders, then reinstalled (twice).... didn't help.
Reverted PC back to before Firefox updated... didn't work.
Uninstalled, Debugged my PC, reinstalled.... didn't work.
Turned off firewalls & switched settings to make sure nothing was blocking it from working.... didn't work.
At this point, after surfing Mozilla support site & not finding anyone else having this exact issue I'm not sure what else to do. I love Firefox & want to keep using it (I HATE using Internet Explorer) but the only other solution I can think of is use Google Chrome or IE.
I have Windows 7, use McAfee, & SpyHunter. My laptop is less than 5 y.o. & I keep thing updated reg. so I don't think anything should be out of date or incompatible.
Thanks!

Hello,
Currently in version 33, Firefox has implemented a new, faster way of loading webpages. This new feature is called OMTC. However, there are still some tweaks Mozilla developers are making to this.
There is a known issue that Mozilla works on very hard to fix: if you are experiencing black webpages on some sites, here's what you can do to avoid the problem in the meantime:
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>

To disable Hardware Acceleration
* Click the menu button [[Image:New Fx Menu]] and select ''Options''.
* In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
* In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
Now, exit Firefox, wait a few seconds, and then start it normally.
Please let us know if this solves the problem. Engineering is also gathering more information about the issue would request that you fill out [http://www.surveygizmo.com/s3/1851506/1c87a6cf309a this survey]
I should also mention that other users with this problem had an embedded intel hd graphics card with an old driver present. Until Mozilla comes up with a fix, if you want Hardware Acceleration in Firefox, you can try to update your driver through the appropriate link below to see if that helps:
