With Tumblr's new UI changes, XKit Rewritten is a must-have. You can clean up all the algorithmic recommended stuff easily. And this addon does a better job with accessibility than Tumblr ever has...

The essential add-on for a smooth tumblr experience!

The only reason tumblr is usable. I can only hope the dev chooses to continue updating this.

edit: as of 10/9/2025, postblock isn't working. Please devs, fix this.

Honestly makes using my favorite social media 200% more enjoyable to use, the site doesn't feel the same without it

The reason Tumblr is usable! I only wish Firefox on Android devices would support it.
