Firefox not fast enough for video

[Moltke]

Firefox though is a bit too slow, at least with video playback; the audio is fine but there's a lag with video, even with 360p. (I don't need high-res videos; I just want them to be watchable.) I'm not sure whether this is the browser, the way LL is running (on USB, which would be 2.0 on this machine), or the WIFI connection (a Verizon Jetpack, which is a cellular device). I've never seen a lag like this before. If anyone has any ideas about what's going on here and what I can try to speed things up I would love to hear them.

I've seen this before when running distros from USB in live mode. Browsers are a resource hog and need to save plenty of data on disk, since a USB stick doesn't provide nor the space neither the write/read speed they need, it's completely normal they lag a bit. If you install it on the HDD you'll see there's a lot of difference and it'll run just fine.

Hope this helps!
