CSS filtering - some browsers ignore it

[oldsod]

Sorry not to be of any valuable help with this, but possible alternatives are using solutions other than privoxy.
Firefox still has the feature to add in a custom user css (have used with mixed results) . As does IE (for windows users) to add in a custom style sheet.

I still rely on using an extension to add my css to the browsers (chrome and firefox) - for both ad blocking and styling certain web sites. This I use to overcomes the HTTPS sites problem with privoxy unable to natively filter HTTPS.

Best rgards.
