Hello, I use a web frontend for work that runs locally on my server over X2Go for about one year with success. Some months ago I noticed a significant decrease in performance when using Firefox. My server is running Ubuntu 16.04 with MATE desktop, Windows 10 client. Up to Firefox version 39.0.3 performance of loading pages, scrolling, browsing etc. was nearly flawless over a 5Mbit WAN link (with the exception of embedded video elements). However it seems the release of Firefox version 40.0 introduced some changes in rendering (see https://www.mozilla.org/en-US/firefox/40.0/releasenotes/) that do not play nice with X2Go. Further reduction in performance was noticed in versions 46.0 and 48.0. The current release (48.0) even has trouble rendering a plain text document without lag and choppiness. I have tried toggling various flags relating to graphics, compositing, rendering, etc. to no avail. To work around this problem the only solution I have found is to forward ports over a separate SSH tunnel and browse locally, but this is cumbersome to set up every time I need to connect. I have preferred Firefox to Chrome over X2Go because the latter has always been unusably slow; now they are both similarly choppy and slow. Has anyone else noticed this? Any advice or help would be appreciated.
Regards
Jordan
I wonder if the issue isn't specific to Windows 10, I am using Firefox 50,the development version, on a Ubuntu 16.04 workstation (an old Mac Pro 1,1 with Ubuntu 16.04 64 bit) and I do not see any issues with lag.

I should have probably mentioned that this lag also occurs when running the X2Go client directly on the server itself, so it doesn't seem to be an issue with the WAN link, Windows 10, etc. For the sake of comparison I ran Firefox 48.0 via X2Go on another machine on the same 100Mbit LAN as the server, then ran it again in a forwarded X11 SSH session (compression enabled); the latter demonstrated no noticeable lag while the X2Go session struggled to keep up.
