[orca-list] Firefox pages and orca?

[Unix <isfeldt gmail com>]

Hello, I know there was some discussion on this issue a while back, but 
can't find some of the mailings lol. But this is a mostly fresh install 
of sonar mate 2015.3 and I've noticed that youtube in firefox isn't 
accessible with orca, I've so far disabled addons, and ran ff in 
safemode, and still the regular youtube.com says inaccessible. Also 
noticed that when going to a video, say from a google search, orca 
starts reading the page and I can navigate for a few seconds, then the 
page freezes entirely, most the time I have to force kill FF.  Running 
ff 40.0.3.1  I am assuming this is a youtube issue itself since orca 
seems to read most other webpages I've visited.  Anyone had an issue 
such as this? or know a work around? Thanks much!
