Firefox shows black bar in URL

In combination with an Intel graphic card Firefox shows sometimes in the URL line a black bar. There is nor solution for that, just a workaround:

  • Type in the adress line (URL) of Firefox about:config
  • Acknowledge that you will be careful
  • Type in the search gfx.xrender.enabled
  • When shown click with the right mouse button on true and click on toggle, so that the value is switched to false.

If there is nor entry gfx.xrender.enabled (double check that you did not mistype!):

  • click in the white space of the search entry
  • Select New in the dialogue window
  • In the next windows select boolean
  • In 3rd window select false and confirm with ok

Restart Firefox
