I'm running linux, not windows. That is why firefox is used, not IE.
I just installed Pale Moon hoping to use it solely for viewing my cam's, however, in order to use the above posted procedure, the extension has to be installed. It cannot be installed because it is not in the available libraries.
I have not tried the above on my FF v52, but the browser extension directory that had the npapi-vlc extension is not there anymore, presumably the update from the earlier version removed it.
