My website is looking different in different websites. Any update on CSS is not reflecting immediately in firefox but where as safari and chrome show the modification immediately.
Is there a way to add a code which clears the existing cache whenever the website loads and uses the latest style sheet.

This is done either in the http server through the .htaccess file:

Header set Cache-Control "no-cache, no-store"

or through PHP:

header('Cache-Control: no-cache, no-store');

However there is one big limitation; User Settings.  

You have no control over the user setting and the the browser will not refresh cache if the user settings explicitly prevent it;  unfortunately many users have restricted cache setting to optimize response time, especially if they are on a slow connection or use a lot of sites heavy on graphics or videos.

The solution Dave offers is a commonly used approach.  You can just add the version number to the new file.  The only drawback the approach has is if you are delivering static pages with the file names hard-coded; in which case you will need to change the file name on every page.
