[CS-FSLUG] Is FireFox anti-microsoft?

[Frank Bax]

Are there any other file systems besides MS that either use drive letters 
or do not have a single  'root' directory (MS has a root dir for each drive 
letter)?  I ask because I thought I found a bug in FireFox:
         http://forums.mozillazine.org/viewtopic.php?t=213537
But when I searched Bugzilla, I found this one that seems the same:
         <https://bugzilla.mozilla.org/show_bug.cgi?id=257321>https://bugzilla.mozilla.org/show_bug.cgi?id=257321
Now I'm wondering if the FireFox people have taken an anti-microsoft stand, 
but are pretending not to?
