The newest version of Firefox, 13.0, seems to have a problem playing youtube videos. Whenever I go to youtube and try to play something I get a “There seems to be an error. Please try again later.” At first I thought it was a problem with youtube, and put in an error report with them. Youtube played fine on my earlier Firefox installation, and plays just fine on Google Chrome and IE, so the problem seems to lie with Firefox.
In the past I have had other problems with updates to Firefox. One time I couldn’t see what was in my Google search box after updating. The next update seemed to take care of the problem. I cringe when I see that pop up box that says there is a new version of Firefox available. I wonder what favorite add ons won’t work with this one, and what other problems it might bring. That’s why I tend to wait for a couple of weeks to months before clicking the update button, hoping that maybe the bugs will have been worked out. I normally donate a little bit to programs and projects that try to improve my computer experience for free. Firefox has not given me a reason to donate. I have read the solution for uninstalling Realplayer and rolling back Flash, and this doesn't work for me. I use Realplayer all the time on my computer, and Firefox will leave before Realplayer does. If Firefox can't come up with a simple solution or fix then I guess Chrome is in my future.
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox 13 are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
