Was discussing how used to be able to watch videos on early x2go butnot anymore. It was said to be a firefox issue. I found an interesting note in a vnc article but it might be applicable to x2go:
On XFree86/Xorg it is actually possible to increase the framebuffer read speed considerably (10-100 times) by using the Shadow Framebuffer (a copy of the framebuffer is kept in main memory and this can be read much more quickly.) To do this one puts the line Option "ShadowFB" "true" in the Device section of the /etc/X11/XF86Config or /etc/X11/xorg.conf file. Note that this disables 2D acceleration at the physical display and so that might be unacceptable if one plays games, etc. on the machine's local display. Nevertheless this could be handy in some circumstances, e.g. if the slower speed while sitting at the physical display was acceptable (this seems to be true for most video cards these days.) Unfortunately it does not seem shadowfb can be turned on and off dynamically...
Wonder if tweaking with this could benefit x2go response?-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

No.
That's because unlike VNC, NX does not capture the content of a remote framebuffer (=the server side), but does the actual drawing *right on the client*. Which is why you need a client-side X Server. So there is no server-side X server in use that we could apply this change to. And like the text says, if you try to do it on the client side, you will actually slow it down even further, because you disable 2D acceleration.
For the upcoming X2Go-KDrive, it might help - but KDrive only works with full desktops, so it's no replacement for NX.
So if you want a fast Web browser with X2Go, I can only repeat what I wrote previously: Help us get Pale Moon 28 up to speed again, either by volunteering time as a tester, or by paying someone to work on the code.

It might also help if I got a modern computer on the client side.I'm using a 2005 vintage Mac Pro 1,1, the very first Intel based Mac. Quad Xeon 2.6 Ghz CPU but memory bandwidth is horrid owing to buffered registered memory. THe video card was also antique. Never the less used to be able to watch video over x2go and this was actually far past the point where you say Firefox went to hell. It was about up to the point where they changed the plugin interface to be useless.

As I've explained before - Firefox changed the way they render the page. They are making heavy use of advanced graphics card features - but, these are unavailable via NX, no matter how fancy your client-side *or* your server-side graphics card is.
So the only way to speed things up would be to get a faster network connection - which kind of defeats the purpose of NX.
Trust me, if there was a way to weasel around this Mozilla bullshit, we would have recommended it long ago.

Ok, but Mozilla worked okay for me far past the point you indicate thischange was made.
