SO after all this nothing changed so I went further into the thread and found these additions, I'm not sure if one or all of them made the difference. (boolean, true defaults to false if you downloaded a DRM-free version of FF (integer, 1500000000 not required, you can set it if you want to more closely mimic automatic install) (string, x86-msvc-x86 not required, you can set it if you want to more closely mimic automatic install) (string, 17 required for manual install now that automatic install is no longer an option) (boolean, true FF 45-48, no longer used in 49.0+) Then I added/edited these 9 lines in about:config as described. BTW I'm running winxp 32 w/sp3įirst I added the files into my FF profile folder as described on post 1.

Since I run a portable version of firefox 48.0 I made a mirror copy of that to alter in case I messed up. First I tried the latest FF portable 52.2.1ESR but still no joy. I was having trouble viewing particular html5/h.264 videos and the like on firefox portable 48.0, test pages showed negative for h.264 support. Ok after hours I finally got it to work but it took additional steps not mentioned in the initial post I had to jump around to find enough info.
