how do i get css source file path from firebug?

I need to modify a couple of classes in the css of the site i'm currently woking on. an开发者_如何转开发other person worked in it, so i really don't know where he has put the styles. i know firebug shows the css path on the corner, but it's just showing the url like this: http://localseo.org#3(line 149) . what does it mean? how do I get the file path? Thanks for the help everyone.

Click on that URL.
It will open the correct file to the correct line. From there you can easily see the path...

However, if you mean file path, on the server, you cannot get that from the browser or Firebug; it depends on your server settings.

Open firebug and you'll see a CSS pane/tab you can then select the stylesheet you want/need to edit.
