Re: [Trisquel-users] Gnash Not Working

[onpon4]

As far as I'm aware, Gnash only works on YouTube and some very old Flash  
media. I suggest disabling it; many video streaming sites have fallback  
HTML5-based players that only show up if Flash is not available. For YouTube  
videos, I suggest either ViewTube (a Greasemonkey script) or UnPlug (a  
Firefox/Abrowser extension), or perhaps both. These both also work on several  
other sites (especially UnPlug). You may also want to install the user agent  
switcher extension; apparently, some sites have fallback HTML5-based players  
that only show up if your browser identifies itself as an iPad.

I checked that website you mentioned; it has a fallback HTML5 player if you  
disable Flash, and it also seems to work with UnPlug.
