I've been using this app for a very long time, and for the most part I love it, and often recommend it to others. But recent changes are the reason for only 4 stars: I wish I could still list blockees individually, and DEFINITELY wish I could easily turn it off for a particular page. Updates are not always improvements.

Love the idea but it misses a few and gives a few false positives too where it replaces random images with cats. Allowing a whitelist of sites would be useful.

Really hate that the ability to make a list of these awful people to be blocked has been removed. It was awesome before, now just good.

Does not work on duckduckgo, google or msn website :( CNN works :)

Funny and enjoyable, though it's not catching as many unpleasant images as it used to. Still, I'm as grateful for this extension as my computer is for virus protection!

This gem is the helper we need today! It does wonders for my mental health during election seasons and unwelcomed trends. Users can quickly strengthen the kittens' power by adding anything -- not just people names. Hate Hitler _as_you_should_? Add "Hitler" and boom! He's gone. Block his underlings by adding "führer." Speak American? Include "fuehrer." Hate Portland _as_you_should_? Add "Portland, Timbers, Rose City." It's almost perfect -- I'd love an onclick "Add" function. Kudos and thanks to tomroyal.com. Please never retire this this valuable coping tool; It deserves universal adoption.

Will you adding the menu item to undo kittening, like the Chrome version? That would make it five stars.

Edit: until then, extension users can get the unMAKA functionality by making a bookmark with the following URL:
javascript:(function () { for (var i of document.getElementsByTagName("img")) { if (i.hasAttribute("makareplaced")) { i.setAttribute("src", i.getAttribute("makareplaced")); } } })()
