I'm trying to view an RSS feed in Firefox, but am getting the following message.
Your RSS reader does not support (gzip) compression.
Is it possible to enable GZIP compression in the Firefox RSS Reader?
Turns out, the corporate web filter alters the request, removing the "gzip" support. This may be quite localized, but at the same time, if you are behind a web filter of any kind, that may be the issue.
