How to disable GZIP compression in Firefox

Not sure this is the only/best way but I used the following steps to disable gzip compression in Firefox 3.0:

1. Type about:config in the URL bar (Accept the disclaimer)
2. Type encoding in the filter field underneath the URL bar
3. Doubleclick the line network.http.accept-encoding
4. Enter the following value instead of the default: gzip;q=0,deflate;q=0

Note: See comment from Anonymous below for a possible better way of doing this. Thanks Anonymous!
