firefox no longer starts - could it be wayland package?

[Genes Lists <lists@xxxxxxxxxxxx>]

Running on gnome

This may have to do with updated updated wayland package (1.22.0-1) - 
didn't see much else that may be related.
I tried rolling back firefox and makes no difference - I also tried with 
and without MOZ_ENABLE_WAYLAND - always get instant crash with:

ExceptionHandler::GenerateDump cloned child 5628
ExceptionHandler::SendContinueSignalToChild sent continue signal to child
ExceptionHandler::WaitForContinueSignal waiting for continue signal...

Anyone else seeing similar and any suggestions for fix?

thanks
