Build ID: 20160120202951

Steps to reproduce:

Tried to play any Brightcove video embedded in a website.  Mostly the videos are from UK news sites ie Mirror.Co.UK.

Actual results:

Embedded video of Brightcove will not play in Seamonkey browser on my desktop.  I have just noticed this in the last Couple of months.  It will play on IE but not Seamonkey.  Most of the videos are from news websites in UK ie Mirror.Co.UK.  I am currently using Seamonkey ver. 2.40 as there has not been an update in a long time.  When I click on the video to play it, the screen just shows it buffering with the spinning circle.  I can leave the page up for an hour and it just looks like it is buffering and will not start (no error message).  I can always find the video on Youtube and the same video will play there fine.  I am using Windows 7 as my OS.  Seamonkey has HTML5 and I also have Flash loaded.  Try this video (if it is still there)

Expected results:

Video should play.

REPRODUCIBLE with  en-US SeaMonkey 2.40 final Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) from official download page,  Gecko/20100101  Firefox/ 43.0  Build 20160120202951, (Default Classic Theme) on German WIN7 64bit:

1. Launch Browser → menu ˋTools → Switch Profile
   → Create and use new user profileˊ
2. Visit <> → Click “Play”-icon in movie preview → Confirm all warnings if necessary
   Expected: movie starts to play
   Actual: endless loops of buffering, in Status Bar endless “Transferring ...”,
           but video will not play

a) NOT / no longer reproducible with official  English 
   SeaMonkey 2.46 RC (Build 9)  (Windows NT 6.1; WOW64; rv:49.0)
   Gecko/20100101 Firefox/49.0 Build 20161213183751(Default Classic Theme)
   on German WIN7 64bit
b) Has nothing to do with movie itself, <> plays fine
c) I did not find a security preference where changes heal the problem, but I did
   not test intensively
d) I don't know what the root of the problem might be.
e) CLIQZ 1.8.0 and 1.9.0 show similar symptoms, so probably not a 
   “SM only” problem.

Can you confirm WORKSFORME with 2.46 from <>?
