[X2Go-User] Issues running firefox 45.0.2 remotely with X2go

[Rett D. Walters]

Stefan:

Thanks for your prompt reply.  I was running a full Xfce4 desktop in an 
X2go client session and running firefox from there to create the error.

Interestingly enough, the "published application" mode actually works 
fine.  Never used this feature before with X2go.  For some reason 
firefox doesn't crash this way.

The --ProfileManager and --safe-mode options don't have any different 
results with full Xfce4 desktop in a x2go session, Firefox still crashes 
shortly after start up.  Interesting thing is it will stay running until 
you move the mouse in the session (or type something), it will then 
crash.  If mouse isn't hovering in the firefox window on the desktop 
session when you move it doesn't crash until you move it over the 
firefox window.

Tested it with x2go session running twm and it doesn't crash there. 
Seems like its specific to Xfce4 only, but it does work fine on the 
server's local X console running Xfce4.

Guess I will put a post on the x2go-dev list on this issue.

Thanks,

Rett Walters
