Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:

  • Windows/Mac: Go to Help > Restart with add-ons disabled
  • Linux: Run firefox -safe-mode in the Terminal/Konsole

If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

no change whatsoever when starting with add-ons disabled and in safe mode. opens the netflix website just fine but when you go to play any netflix video says there is a error with silverlight. I also tried uninstalling and reinstalling with the add-ons disabled to the same effect.

Silverlight shows as Version 5.3.1.18536 in the System Details list.

If you use extensions (Firefox/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.
