Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

You can use one of these to start Firefox in Safe Mode:

• On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
• On Mac, hold down the Options key while starting Firefox
• Help > Restart with Add-ons Disabled

• https://support.mozilla.org/kb/Safe+Mode

Could you start Firefox in its Safe Mode? Firefox's Safe Mode is a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Use Troubleshoot Mode in Firefox.

If Firefox is running: Help > Restart with Add-ons Disabled

If Firefox is not running: Hold the Shift key while start Firefox

Then, in the dialog, click "Start in Safe Mode" (not Reset)

The hardware acceleration feature is sensitive to graphics driver incompatibilities. Disable it here:

orange Firefox button (or Tools menu) > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

Then exit and restart Firefox normally.

Any improvement?

Assuming you can read the toolbars in Firefox, can you look up your current version using Help > About Firefox?

Edit: I guess version 7 rev 25 may have been a Java update.

Thank you for the assistance. I can now use Firefox once again. I disabled the hardware acceleration and that did the trick. I have since made other changes that I wanted.

And you are right, I was referencing a java install when I said Version 7 - 25. Sorry I mixed that up.

I appreciate your willingness to help. Kerry

Thank you for your help. Since I couldn't see anything but BLACK on Firefox, I was operating blindly . . . . . not a good thing. I appreciate your willingness to help. Kerry

I have this problem as well. I wish I could use tools but I can't see anything on the menu at all.

I received this information and it works: Try to disable hardware acceleration in Firefox.

Do you still have problems or did disabling hardware acceleration fixed all issues?

There was no hardware acceleration checkbox.

There was no hardware acceleration checkbox. Firefox version 22

I used nightly and the black screen happened. I went back to regular firefox, by installing it after uninstalling nightly using revo unistaller, but black screen remains.

Hi wolbar, the location of the Options/Preferences dialog in the menus depends on your operating system, but once you locate it, there definitely should be a checkbox for hardware acceleration in the Advanced options. Do either of these articles help:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
• Advanced panel - Accessibility, browsing, network, updates, and other advanced settings in Firefox
