At the moment the protocol handler API we use does not have a concept of headers, so if the issue is a lack of Content-Encoding header, then this cannot be easily added. The other solution would be to decompress inside this extension, but I'm not sure I want to ship a javascript gzip implementation with the extension. There are Firefox APIs for doing gzip natively, but that would require another experimental API to expose that API to the extension.
