Netscape sometimes gets scripts messed up and stops loading the page at certain points. This is a side effect of reading html/php/etc written specifically for IE.
PHP can't be written specifically for IE... maybe Apache vs IIS might be slightly different.
HTML doesn't really change at all between the two... they might do things slightly different, but html is still html.
The biggest problem is CSS...
Firefox likes to play with tables dynamically... it'll load the first row and then after loading the second row, it seems to decide whether or not to change the soft values of a table... maybe you got stopped before firefox decided to fix it.
Anyways, as stated, it's not a bug if it only happens once or only happens for you... if it's not reproducable, there's nothing much I can do about it.
