/////////////////begin css file////////////////
anything wrong


body {  font-family: "arial, 宋体"; font-size: 9pt; line-height: 13pt;
background-color: #E5EFE0;}
table {  font-family: "arial, 宋体";font-size: 9pt; line-height: 13pt;}

/////////////////end css file////////////////

above is a sample css file, there is an unecessary/wrong enlement "anything
wrong" on top, this will cause the first style -- "body" be ignored by firefox,
adding blank lines after the wrong line won't fix.

if we modify it to

/////////////////begin css file////////////////
anythingwrong
wrong again

dummy {}
body {  font-family: "arial, 宋体"; font-size: 9pt; line-height: 13pt;
background-color: #E5EFE0;}
table {  font-family: "arial, 宋体";font-size: 9pt; line-height: 13pt;}

/////////////////end css file////////////////

then every style seem to be processed, so I conclude that the first style be
ingnored/wrongly processed by the processor, and also adding any more wrong
lines won't cause more style to be ignored.

Reproducible: Always

Steps to Reproduce:
1. add any wrong lines in front of an external css file

I changed the Severity to "minor", sine it should be a fault-tolerance function

how are you proposing that Firefox determine where the unnecessary stuff ends
and the first style begins?
