Firefox does not complete startup.

Posted

Does not open a startup page. Stops when the initial Firefox grey-out displays (Tried to send screenshot. Upload still churning after several minutes). Firefox Icon shows in current apps list and can be Force-Quitted. Does not appear in the Recent-Apps menu.

Began when I clicked on a Steam/Rimworld Button link to "Rimworld User Forum". Didn't show URL.

Note that the OP is using Mac OS X 10.11.6

Try to start Firefox in Safe Mode to see if that works.

  • Mac: hold down the Options key while starting Firefox
  • Windows: hold down the Shift key while starting Firefox
