This add-on has saved me from so many annoying posts. Thank you!

It's an amazing extension. It really saves me from seeing posts of things I do not want to see... but sometimes it doesn't hide things (mostly the junk on the sidebar).

Works great and hugely improves Tumblr for me.

As of December 16th 2017 this extension is working again. As of the time of this writing I'm using Firefox Quantum version 57.0.2. The previous reviews are several months old.

You're probably going to need this to avoid star wars spoilers, and the like.

Makes Tumblr bearable again, thank you!

Does exactly what it says. Removes ads and hides blacklisted posts. Tags for blacklisted posts are still visible so you can decide whether to view the post or not. I like how easy it is to restore a saved list since I need to refresh Firefox sometimes and that deletes all addons.
