Instead of dragging and dropping the Pin It bookmarklet, users can add the Pin It option to their right-click functions via a few clever browser add-ons:
Google Chrome: Google Chrome users can visit the Chrome Web Store and search for Pinterest. Right click Add On and click the Add To Chrome button. Next, right-click on an image you’d like to pin. The Pin It option will appear in the drop-down menu.
Mozilla Firefox: Users should go to the Mozilla Firefox home page, mouse over the Add-ons tab and select Desktop Add-ons. Next, search for Pinterest. Right-click Add On and select Add To Firefox. Click the Install Now button in the subsequent pop-up window. You’ll receive a prompt to restart Firefox with a notification that the add-on will be activated after the restart. After restarting Firefox, find an image you want to pin and right-click.
