  • url:
    theme: subtle by
    wordpress version: 2.6

    If you take a look at the site using Firefox 3 you will notice that the white container for the body of the text is broken, and a large section is off to the left by a single pixel. This problem doesn’t happen with any other browser, just with Firefox 3.

    Does anyone have any idea about what might be causing this problem?

  • that happen because firefox 3 (& opera 9+) fully support CSS 2.1 specs but not firefox 2.

    here’s some code add in your theme’s functions.php.

    function embed_gecko_styles(){
     $ua = trim($_SERVER['HTTP_USER_AGENT']);
     $firefox_majv = 'Firefox/3'; // firefox 3 specificly
     $release_version = 'rv:1.9'; // gecko like 1.9 engine
     if ( strpos($ua,$release_version) || strpos($ua,$firefox_majv)){
    <style type="text/css" media="screen">
    	#header,#footer{margin-left:-1px !important}
    if ($is_gecko){

    Hi Kaizer,

    I tried pasting that in various places in my functions.php, each time getting a sidewide error and having to manually overwrite with the original.

    The error message begins with:

    Parse error: syntax error, unexpected T_IF, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in…

    I understand that this an issue related to standards and compatibility, but I’m wondering if there is a fix. Otherwise I’d have to choose a different theme.

    I dont find any syntax error with my code.

    Kaizer, thanks for posting your fix here. Which part of function.php file do you paste that in? Is there anything else that I need to modify in order to add this function?

    Update: I tried using a different theme (which doesn’t happen to have any rendering issues with FF3) and I didn’t have any issues adding that function to functions.php. Actually the functions.php for that them didn’t contain any other functions.

    Just in case anyone wants to take a look at the function.php file of the theme that I’m trying to fix (the one that’s giving me the error when I add the above function), I’ve posted it at

    P.S. Kaiser, your own blog also seems to be broken when using FF3.



    Wondering if anybody else is having a similar problem, or using this theme?
