Grid sort problem

[Fuzzbucket]

When I try to use grid sort on some browsers I usually get an error:

 

 

and sometimes there is a bar at the bottom saying it has completed a handshake with cloudflare.

 

Or "waiting for s.dcave.net" after which mostly it says "read s.dcave.net".

 

Is there anything I can do about this other than switch browsers ? (most recently this was on Pale Moon.) I tried debug and stop script - no effect at all.
