I have recently installed 16.04 as a replacement for a 14.04. Reinstalling flash plugin with pipelight, I have followed the french ubuntu page for installing pipelight. Everything seems to work fine except when at the end I go on the about:addons page from mozilla, I do not see shockwave, Cisco H264 is the only addon installed... I have redone the all procedure twice, same issue. Any hint?
With Mozilla/firefox closed, run the following command:
sudo pipelight-plugin --create-mozilla-plugins
Open Mozilla and check about:plugins
: it should now be listed.
You will probably have to do this every time the plugins are updated.
