Browser tools and extensions covers add-ons, userscripts and utilities that change how you browse the web. Listings include extensions for Chrome, Firefox and similar browsers, along with userscripts, bookmark managers, tab tools and privacy add-ons. Some entries are official store pages, and others are open projects you install from a repository. The permissions each add-on requests, the last update date and the number of maintainers tell you a lot about it. Extensions can read and change page data, so install from a source you trust and confirm what the add-on actually does.
