Firefox päivittyi versioon 19.0 jonka jälkeen selain on vain musta ruutu. Poisto ja uudelleen asennus ei auttanut. Viruksia tms ei ole. Muut selaimet ja tietokone muuten toimivat normaalisti. Latasin vanhan version ja se toimi normaalisti, kunnes päivittyi seuraavan käynnistyksen yhteydessä uusimpaan versioon ja musta ruutu palasi. Nyt en saa edes mitään vanhempia versioita firefoxista toimimaan, nekin näyttävät kaikki mustaa ruutua.

Try to disable hardware acceleration in Firefox.


A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Firefoxin palauttaminen – lisäosat poistetaan ja asetukset palautetaan article.

Thank you for your answers. Unfortunately I can't try your fixing suggestions because also firefox menu doesn't seem to exist anymore. (attached a picture of my firefox)

I checked the firewall and anti-virus, they don't block firefox.

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

Previously even safe mode resulted in black screen but fortunately I now tried it again and this time it worked. Resetting firefox didn't fix the problem, but disabling hardware acceleration did. It's working again, thank you!! :)
