Turn Hearthstone card names into links with tooltips.
Updated for Whispers of the Old Gods!
The Hearthstone Linkifier browser extension searches through any web page for plain text card names and turns them into Hearthhead links with tooltip popups displaying all of the card's stats.
To use Hearthstone Linkifier, just right-click on any page and select 'Linkify Hearthstone cards.' The extension will begin converting card names into links, with a progress indicator in the lower right corner of the page.
You can also set the extension to automatically run on specific pages of your choice. Check the extension options for more information.
