"OpenH264" prevents Firefox 33 on Yosemite from booting.
I deactivated all plug-ins and the Cisco plug-in is the culprit. Yosemite was installed on a clean, newly formatted disk. Deactivating and loading each plug-in one-by-one showed the Cisco plug-in to be the culprit. Can anyone provide and information or solution?
UPDATE! I've been doing a clean install of Yosemite all weekend and many of my automattion software and applescripts are not yet installed, so I've been using Launchbar to launch programs, often not looking at the pop-up once I type in "FIre." It turns out that Firefox in launchbar shows about 3 results and clicking on the wrong one gives the error I was experiencing. Once I realized that, the problem has disappeared . . . Thanks to all you replied.

You can try to disable the OpenH264 plugin in "Tools > Add-ons > Plugins" or set the media.gmp-gmpopenh264.provider.enabled to false on the about:config page page to see if that helps.
Gecko Media Plugins like the OpenH264 from Cisco are installed automatically in current releases and can only be disabled via the about:addons page.
Thanks for your reply. Turns out it apparently may not be the Cisco plug-in, since disabling it seemed to solve the problem, which occurred again after a few shut-downs. Ditto with all other plug-ins, turning them off-and-on. The problems seemed to be solved by de-activating one, then the other, then another. I might try an un- and re-install. Never happened with Mavericks. Don't know if the issue is with Yosemite. Meanwhile, back to Chrome.

Are there still Firefox processes running if you check that in the activity monitor?
