No, Firefox (or specifically Debian's rebranded version which they call IceWeasel) does NOT run with acceptable speed over a remote X session, although this might in part depend on the hardware platform. I'm afraid I can't test this in detail at present due to Debian self-destructing after an update to one of my development systems, but so far it appears that I get exactly the same combination of problems as we've previously discussed with Lazarus. I was going to comment on this publicly after I'd tried to characterise the Mozilla problem a bit more, but at present I'd suggest that it's either a bug inside GTK2 itself or is associated with a particular way of using one or more GTK2 facilities. This appears to be worse on SPARC than on x86, it would be interesting to know whether it is predictably worse on big-endian than little-endian systems. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] _______________________________________________ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
