Well i use lubuntu 14.04 and i've realized that the html5 player on youtube works so much better than the flash player, but i can't use it by default, for play videos i have to request the html5 player, and the problem is when i restart the browser or when i turn off my computer, big is my surprise because youtube is using the flash player. If i disable the flash plugin is ok because youtube doesn't have another option but to use html5, but this is not the solution, because there is still some videos that use flash, and other web sites too. so: how can i fix this or i just have to wait that mozilla gives html5 support for linux, because on windows the default player is the html5. i'd really appreciate any help, thanks
