Whenever I open an XML file in Firefox, the tags are all stripped off and I see just plain text like this [[http://i.imgur.com/pBhUM.png|XML File 1 in Firefox]]. The same file displays in Internet Explorer like this [[http://i.imgur.com/CT8Zb.png|XML File 1 in Internet Explorer]] For an average user, this is the preferred view, as he can see the text content of the XML file without worrying about the tags in the document. For other more advanced users like myself, this is very inconvenient. There are even some cases where Firefox does not display anything because all the tags are stripped off like in this case [[http://i.imgur.com/hAkBd.png|XML File 2 in Firefox]] here is the same file in Internet Explorer [[http://i.imgur.com/juOzs.png|XML File 2 in Internet Explorer]]. The workaround I use now is to view the file's source so that I get to see everything. I must say, however, that this is very inconvenient. If the user does not specify any style sheet for formatting the XML file, I believe the file should be left as-is; it should not be touched. Kindly review this so we can confidently use Firefox as our default browser without having to switch to IE from time to time.
