The “html.css” is very mysterious to me, it always suddenly appear and suddenly disappear, when it appears, it always destroy my page style and keep sticky there until God knows when it disappears
Is there a way to disable it ? How?
Add: i found the problem appears not only in my system but also in my guest os, so i guess i have to found the cause and fix it as it may also appears in site visitors computer
html.css is default stylesheet of firefox. you can find more info about it here and here
and when you asked about disabling it , did you mean to over-ride the default behaviour ?
if yes, you can use reset the default style sheet,
there are several ways
