First, "DeflateDisableRange" doesn't disable gzipping - it disables
partial responses (byte-range) if this request can be gzipped.
If you want to disable gzipping for some browser you need to set
enviroment variable:

BrowserMatch "Gecko" no_gzip

Second, don't use "Mozilla" string - this string is in all Netscape 1-6,
and MSIE 1-6. Use "Gecko" instead - all Mozilla-derived browsers has
this string.

And third - can you send me all bug reports with Mozilla ?
