Mobile Finder от Ashforge Addons

Mobile Finder makes it easy to switch between desktop and mobile versions of websites.

With a single click, Mobile Finder attempts to locate and open the mobile version of the current website. Depending on the site's design, it can open the mobile page in the current tab or a new tab. When a dedicated mobile version isn't available, Mobile Finder will let you know rather than redirecting you unexpectedly. Mobile Finder is part of the AshForge Addons collection, a growing suite of Firefox extensions focused on enhancing and simplifying everyday browsing while building on Firefox's existing features rather than replacing them.
