I've installed Dust-Me Selectors into Firefox to investigate the CSS on my site.
My aim is to find redundant CSS - I want to clear out the rubbish.
The program installs fine. It appears to work on single pages. But I can't spider the entire site. If I try to spider my site map it runs for a few seconds then an image of the site's front page appears in the spider window along with some code.
Is there any official support for the tool?
