Google Cache Checker is a handy Firefox extension that lets you instantly check if the webpage you're visiting is indexed by Google. This tool is perfect for bloggers and website owners who want to know when their latest articles are indexed or if any of their pages are missing from Google's search index. The extension adds a small icon to Firefox's status bar, turning green if the page is indexed and red if it's not. Additionally, if the page is indexed, you can access the cached version on Google and see the date it was last saved. Enhance your SEO efforts with Google Cache Checker and stay informed about your site's indexing status.
I had a decent experience with this app. It worked well for finding past web pages, but I found some links were dead. It's helpful in direct searches, just hope it improves on finding all content.
