Hello! Today I started using k-meleon, it is amazingly fast, but I have this problem: I can't watch videos on youtube, instead the video i am looking for, a black screen appears with these messages:

"Your browser does not currently recognize any of the video available"
"Click here to visit our frequently asked questions about html5 video" ,

then when I click on second message, a page with these info opens:

"You're awesome! That's right! Your browser is up-to-date, which means you can use YouTube's latest features. Enjoy!"

And give me a link to go to the initial page of youtube (and also it offers me get the last versions of these browsers> Opera, IE, FF and GC).
I have not these problems with youtube using a Firefox 52.9.0 I used to use nor with a SeaMonkey I am also trying last week. I have an old Windows XP SP3 on an old Acer AspireOne from the last decade :|.
Thank you very much for reading an I hope you can help me!

Pon qué versión usas y otros podrán ayudarte mejor.

En principio, la 76.2 con engine Goanna debería de estar lista para funcionar con vídeos.
