You're right, I'm probably a bit to0 rude with this but it's far too old and most applications just test if GLX is enabled without testing it's version or correct support for each extensions which leads to crashes at times.
Since there is no gain in keeping it "as is" (at least, I did see more problems than gains) and until GLX support is updated through Lib-NX, I personnaly would recommend disabling GLX by default (which let the possibility to the user to activate it if he really needs it but don't make this the default behaviour).
Since applications are checking if GLX is enabled, disabling it force them to fallback on software renderers only (or don't run at all but I prefer that to crashes for unknown reasons).

I know and I upvote for that as top priority since more and more applications needs this.

It is not "unusable". But nx offers an old version of GLX only. And 
there seem to be some applications that don't care for the version the 
X server (nxagent in this case) reports. So what should we do? 

It is possible to implement a newer GLX version but that would need 
some investing quite some time. Unfortunately the current nx 
development staff does not have that time... 


Regarding Thunderbird: does it still crash after setting 
gfx.xrender.enabled to true in about:config (respectively user.js)?
