hello, can you take a screenshot of your problem and attach it here in the reply box, so that we can assist you better. How do I create a screenshot of my problem?

If you are in full screen mode then hover the mouse to the top of the screen to make the Navigation Toolbar and Tab bar appear. Click the Maximize button (top right corner of the Navigation Toolbar) to leave full screen mode or right-click empty space on a toolbar and choose "Exit Full Screen Mode" or press the F11 key.

I have the same problem, nothing shows, not even navigation or menu bar. (see attached screenshot). I have Windows 7. Uninstalled and re-installed Firefox, did system restore twice, didn't fix it. Appreciate any advice!

hello szamos, other users with this problem all had an embedded intel hd2000/3000 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).

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Hi Philipp, the second option solved the problem, thank you!

thanks for reporting back! would you also go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? maybe this contains information that will help mozilla's developers fixing the issue for other affected users...

Happy to do that but my Firefox is in Hungarian so that might pose a problem for the developers :) Here's the plain text anyway:

Kísérleti funkciók

hi szamos, you are the first reporter i saw with this problem which has an intel hd4000 card. can you try updating the driver - this should be the appropriate link for your model and system: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24329

afterwards please test if it' working with hardware acceleration on again & report back. many thanks!

I tried to do this at first but after downloading an error message popped up saying 'The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer’s manufacturer'. Since my IT knowledge is pretty limited I didn't try anything else after that.

ok, this probably means that you own a device (probably a notebook) where the manufacturer has disabled the installation of generic intel drivers. if you could tell me what device you're using (manufacturer, product name), i'll have a look what options are available for that...

It's a Dell Inspiron 15 3521.

argh, unfortunately dell made no further updates available for that model, so you'd have to stick with just keeping hardware acceleration disabled.

No problem as long as Firefox works OK without it :) Anyway many thanks for your help, I really appreciate your efforts!
