Already done on both. This is also a tweak I have used with IE for a long time, and is one of the first things I did with Firefox (the RFCs be damned.)

It might be interesting to see if you run into the same discrepancies and problems if you set them both back to the system defaults.

Lately I've been getting a problem with my dialup connection where the line drops if I'm streaming too many pieces of data down the line at once. I've just now set up both IE and Firefox so that they're back to the defaults again, I'll see if the problem goes away...
