Browser extension for Chrome and Firefox that replaces images with similar images, except with cats.
- Only replaces images that have some metadata available (ex. alt-text)
 - Easy to disable on any site
 - Option available to show dogs instead of cats
 - Caches recent images for faster loading times
 
- Install Prrrowser from the Chrome Web Store
 - Install the Firefox Add-on
 
Right-click the Prrowser icon to open the menu.
- 'Show dogs' will toggle on for dogs, off for cats (default is cats)
 - 'Disable on this site' to easily disable Prrrowser on any site
 - 'Options' -> 'Low resolution images' (Chrome only)
 - 'Options' -> 'Allow in incognito' (Chrome only - Firefox extensions work in Private Browsing by default)
 
Prrowser uses the alt-text or title of an image and searches Google Images for
'that string' + ' cats'. The first result is then resized and placed where the
old image was. If no metadata is provided, the image will not be altered.
