  since upgrading to rawhide, numerous operations in firefox are just

that hasn't helped noticeably. anyone else running across this? any
simple advice?

You running firefox-28.0.[123]?

I noticed that xulrunner-28.0.1.fc21 "failed to build".

Running latest firefox with older xulrunner spews my journal, etc.

I've downgraded to firefox-27.0.1-2.fc21.x86_64 and all is well.
