What ho one and all,

My wife is using Firefox 52 ESR on an XP / sp 3 computer. Everything was working fine, until around one week ago, when she has started to receive 'Error Code 4' messages when trying to view, for example, TED talks. She is Japanese (not hat that has anything to do with it) and when she is viewing the Japanese Yahoo news site, again, any videos, and the same message.

I have been Googling but everything tells me about 3Play Media and I have no idea what the is. She certainly does not have 3Play Media installed or running.

What can I do to 'fix' this issue?

Any suggestions will be gratefully taken on board.

Thanks and toodle pip

Rex
