Browser Watchdog is a utility to analyze all installed extensions in your browser. It looks out for bad ones, such as advertising, privacy, or malicious ones. If your browser is slow and it looks like it's trying to do too much, it might be the result of a bad extension. This tool can help you get rid of the problem. 

You can find the list of extensions and their version, location, and permissions. You can also find information about the history of changes made to these apps and versions. Once you find a suspicious app, you can click on the Remove button to get rid of it.
