[solved][firefox] HTML5 mode not enabled in youtube

Hello,

I notice since firefox 40 that in youtube the "HMTL5 mode" is not used when I want to read videos,

it's the flash plugin who is used instead of html5,

it's not normal because few days ago I could read videos in youtube with html5 mode,

Am I alone with this problem ?

Is a bug in firefox 40.0.2 related to html5 ?

thanks

I find the guilty : it was the flashblock extension,

if I disable flashblock then the html5 mode is used in youtube

What are you using flashplugin for? Disable plugins / addons and try again.
Go to https://www.youtube.com/html5 and check if you told YT to use html5.
Do you have all video-related optional dependencies for firefox installed?

Edit: Ah, OK :-)

I found the solution : it was the flashblock extension the guilty,

if this extension is enabled then it triggers a bug with youtube : html5 can't work and it's the flash plugin who is used in youtube,

disabling the flashblock extension is to solution, I can now read videos in youtube with html5 mode

Yup, I did read your post. We posted at the exact same time :-)
I'm just curious if you need flashplugin at all.
