Zotero senses information on web pages through site translators, and a Zotero icon will appear only if a site translator recognizes the page being viewed. Zotero's translators should work with most library catalogs, popular websites such as Amazon and the New York Times, and many gated databases.
If a site isn't currently supported or a translator isn't working, you can still save any web document, though you may need to fill in some details that Zotero couldn't automatically detect.
