XKit Rewritten v1.1.0: Classic Footer

A new feature arrives! Classic Footer rearranges the post footer into a more familiar shape, including showing each post's total notes.

This is the very first iteration of the feature, with more options and improvements planned for future versions. Please stay tuned!

If you're using Firefox, v1.1.0 is also the first version available to you with a fix for features being unable to insert menu options into posts.

Everyone should now be able to use PostBlock, Mirror Posts, and NotificationBlock unimpeded. Thanks for your patience on this!

This version was approved for distribution by Google on 2025-10-10, and by Mozilla on 2025-10-16. Please allow 24 hours for Firefox to pull the update, or see how to update add-ons manually.

Deprecating New XKit

Hi all, it's been a while!

tl;dr: You should use XKit Rewritten, it's new, shiny, and getting consistent updates. Get it from here: https://addons.tumblr.com/post/661324873572974592/xkit-rewritten. If you want to customize the appearance of Tumblr you should use the built-in settings or Palettes for Tumblr. You shouldn't rely on New XKit, it's old and busted.

Around four years ago, April, a core contributor to New XKit, started the XKit Rewritten and wider @addons projects to create a modern alternative to the already somewhat moldy New XKit. This was with our complete support, and many members of the New XKit team now also help out with XKit Rewritten and other addons.

Chrome and Firefox have both phased out support for older extensions, requiring challenging workarounds to install New XKit. It's become very clear that anyone who is still using New XKit would really have a better time using XKit Rewritten, Palettes and Outbox for Tumblr, and the couple XKit-inspired core Tumblr features.

If you continue to use New XKit for some key part of your Tumblr workflow be warned that it's past the end of its digital lifespan. Despite the name, New XKit is a crumbling old cathedral. You can still walk around in it if you really want to, but it has been fenced off for safety and a brick might fall on your head.

One key difference we'd like to highlight is that XKit Rewritten intentionally doesn't have a Blacklist feature, leaving it to Tumblr's native post filtering functionality. If you still need the specific functionality of New XKit's Blacklist, you can keep it installed alongside XKit Rewritten. Click here for a list of other frequently asked questions.

To summarize: Get XKit Rewritten here: https://addons.tumblr.com/post/661324873572974592/xkit-rewritten. It's like New XKit but designed for modern Tumblr and consistently updated. New XKit will still be around for anyone who really needs it but is a much buggier experience.

Thank you all very much for using New XKit! On behalf of the whole team it's been a great time with all of you here on [tumblr].

[new-xkit-discussion]

Not sure where best to ask this, but should I deinstall New XKit and only use XKit Rewritten? Or do they need to be used together in order to work?

You can use any combination of the two that fits you. XKit Rewritten is a completely separate extension which does not make any features in New XKit magically work again, nor does it rely on New XKit to work itself. The two do not conflict, either.

If you have reasons to keep New XKit installed, keep it installed. Tumblr isn't done updating the web experience, so features that only run on legacy-powered pages like Mass+ and Go-to-Dash remain exclusive to New XKit for now.

April's Week in Review (21st Jan 2022)

🧩 XKit Rewritten

An option has been added to Tweaks which reverts the post footer redesign. This solution is temporary, but should work until the redesign is a little more final. Make sure you're using XKit Rewritten v0.14.0 if you don't see this option yet.

A new feature, TimeFormat, has been added to allow Moment.js-style customisation of Tumblr's own timestamps! (You can enable Tumblr's timestamps in your dashboard settings.) This feature supercedes the Timestamps feature, which will be removed at a later date.

No Recommended now includes an option to hide recommended posts on the dashboard, which is enabled by default. It does not target posts from followed tags, which can instead be disabled in your dashboard settings.

Fixed some styling issues with No Recommended's "Hide related posts in the photo lightbox" option.

A new feature, Collapsed Queue, has been added to make it easier to navigate queue and drafts pages.

A new feature, Scroll to Bottom, has been added to make it easier to load all posts on a page.

PostBlock's options now lists each individual post ID you have blocked (oldest-first) with individual unblock buttons.

AccessKit now lets you choose if the "Show alt text as captions below images" option will display all alt text, or only set image descriptions.

AccessKit's "Disable layout element animations" option now entirely hides the floating heart animation when you like a post.

The work I do is made possible and kept free by my sponsors on GitHub. Becoming my sponsor is as easy as creating a GitHub account and connecting your Pay​Pal account or card details.

Hey all! Just wanted to pop in and let you all know that April went and added two very heavily-requested features to XKit Rewritten: a tweak to restore the old post footer, and fully-customisable post timestamps. Go check it out!

I think this is overdue a proper announcement!

If you're unaware, I'm one of the members of the New XKit team. It's no secret though that New XKit is kinda dead in the water, thanks to Tumblr's overhaul of its interface which broke almost every feature we had. Oh, and everyone else on the team has a day job now, so I decided to take matters into my own hands:

XKit Rewritten is the result of my work of over a year, now available for Firefox and Chrome (and by extension, Edge and Opera too). There are still features to be added, but the featureset has now mostly overtaken the current working featureset of XKit 7.

If you're already an XKit user, I heartily recommend trying the new experience - even if it means configuring everything again - for its improved performance and increased compatibility.

If you're not already an XKit user, I invite you to give it a go! There's probably some option you'll enjoy. Even if you're on your phone all the time, there's a janky way to set it up on Firefox for Android (sorry, iOS users; blame Apple, not me) which I've also detailed on the wiki.

Have fun with it!

Old Nuclear White Blue

Hey all, you may have noticed that a recent tumblr update broke Old Blue, leading to a dashboard that looked something like this:

I'm happy to report that this is fixed as of Old Blue version 2.1.2. XKit will automatically update over the course of the next ~5 hours, but if you want to update faster, you can go to Other > Update All and click Update all of my extensions to update immediately—but you'll need to refresh your browser for the changes to be applied!

This update also fixes the issue where the XKit button was washed out on the blue background. Thanks for your patience! As always, if you have any questions, feel free to send an ask to our support blog or join our real-time support chat on Discord.

Hi! It’s me, your favourite Tumblr modder. If you liked “Old Blue” in XKit, I’ve got a more lightweight solution for you:

Palettes for Tumblr

This standalone addon allows you to choose a palette from either Tumblr’s list of palettes or a palette provided by the addon. This includes the lighter-blue colour scheme from 2016-2019, and also the even-lighter-blue palette from before that!

This addon also allows you to customise which font type and base font size Tumblr uses. This means you can keep using Tumblr’s Dark Mode palette but still use the old font - or a system font! (Spoiler alert: the Cybernetic palette looks way cooler with Monospace font.)

This addon is currently in beta, and right now is only available for Firefox, but that will change. The end goal is to allow you to create and share your own palettes for Tumblr, and for me to publish the addon on all major browser extension stores.

(Also, if you want to use this, make sure to turn off XKit’s Old Blue or any other palette-modifying userstyles first - they’ll probably conflict!)

[new-xkit-extension]

Hey everyone! We’ve pushed a quick update to Anti-Capitalism to block the large video takeover ad Tumblr is running right now. You can go to XKit > Extensions > Anti-Capitalism, click “Update” and then refresh the page (F5) to get the newest version. As always, let us know if you have any questions!

The Great Tweaks Update of Early July 2020

We’ve added some new features to Tweaks in response to some feedback we’ve heard about the new dashboard. Tweaks version 6.0.1 brings the following changes:

It is now possible to change the style of the notification badges, that show the amount of new posts/messages/etc. in the header. The available styles are Default, Hidden, White, and Old Red (white text on a red background).

There is a new tweak to hide just the activity notification badge.

A new tweak to hide the glow around posts when navigating around the dashboard with the J and K keyboard shortcuts has also been added.

The New Post button in the header can now be turned grayscale, if the bright colour of it annoys you.

The tweak to keep avatars pinned to the top of posts instead of scrolling along has been updated for the new dashboard.

If you’re not seeing these changes show up, make sure you’re on version 6.0.1 of Tweaks, which should update automatically. If you want to do the update manually, open the XKit control panel, go to the Other tab, and click the “Update all my extensions” button. If you are on version 6.0.1 and still have issues with the new tweaks, feel free to join our real-time support chat on Discord.

Tweaks 6.0.2 has just been released to deal with some issues regarding the tweak to keep the avatar stuck to the top of the post. Sorry about that one!

New XKit and the new Tumblr dashboard

Hi everyone! Some of you may be aware that Tumblr has been offering a beta of the new web interface for a little while now. This new web experience comes with some nice perks, such as color palettes, soft refreshing, a built-in tag viewer, and a better user blocking system. It’s also built from the ground up with accessibility standards in mind, and designed to be fully compatible with screen readers.

Unfortunately, such long-needed improvements have come at a price for those that truly rely on XKit features—the new web interface is entirely new, written from the ground up, and thus, XKit doesn’t work on it.

Recently, we’ve become aware that some people have been forcibly opted into this beta with no option to exit it, and this lines up with the projection that this new web interface will be fully launched by April 2020. However, the New XKit project is entirely staffed by volunteers, and we do not expect to have enough bandwidth to be able to fully update XKit for this new dashboard before its full launch.

Update (2020-03-24): Tumblr has introduced an opt-out toggle in the Dashboard Settings for XKit users, which will give us a little more time until the full switch-over.

“Oh no! Tumblr’s trying to kill XKit!”

You would be amazed at what’s actually happening. A few Tumblr engineers are working with us and are building things into the new dashboard specifically to make our jobs easier! So please, rest assured that XKit being broken currently is not part of some grand scheme to make the Tumblr dashboard unmodifiable - we just need more time to catch up, and we’re being helped along.

“But I can’t use Tumblr without XKit!”

This is a problem we see echoed a lot. While we will be updating XKit to work on the new dashboard, we don’t know yet how long it will take us. We’re prioritizing features based on the suggestions you all give, so it’s extremely helpful when you let both us and Tumblr know which parts of XKit are absolutely essential to your day-to-day Tumblr usage. In the meantime, we ask that you try out the new dashboard, with all its new features, and give clear, constructive, and respectful feedback to both us and Tumblr support.

Tumblr has already implemented some equivalents of existing XKit features, and we’re already expecting more to appear down the line. As Tumblr gains a better understanding of why and how people use XKit, we expect to see that list grow.

This is not the end for XKit - merely a stage of metamorphosis. Thank you all for your patience!

[new-xkit-support]

Xkit keeps telling me the auto update won't work. I tried to update manually, but that also did nothing. I followed the troubleshooting, but I could connect to the pages easily, and I have nothing blocking scripts aside from adblock, that, once I paused, did not solve the problem.

Hey all, we’re aware of this issue, it seems to be affecting some percentage of Chrome users (it’s currently unclear how many). We’re working on a hotfix to get it patched. In the meantime—sit tight! Normal XKit updates will be resumed shortly.

(A previous version of this post mentioned additional debugging information we needed—we’re good for now, but thanks for all of the info you’ve submitted!)

[new-xkit-extension]

Thanks for your patience—the fix for this issue has been released! Chrome should automatically update New XKit shortly, but if you want to update quicker, you can do so by going to chrome:​//extensions, selecting “Developer Mode” and then selecting “Update”. This issue has been fixed on New XKit version 7.9.1

Soft Refresh: Infinity Update!

Ever wanted to see new posts while listening to an audio post? Don't wanna load the entire dashboard again just for a few new posts? Broken F5 key? The Soft Refresh extension just got an update that sings your troubles away!

As the title implies, the main feature of this update is that Soft Refresh can now fetch any number of posts. We'd say there's no reason to hard-refresh anymore, but have fun waiting for those 99+ posts to all load in...

The other fun things about this update:

Notifications are now processed!

The extension no longer says "Added 1 new posts"!

Notes containers on soft-refreshed posts aren't weird anymore!

It's tastier!

Not using Soft Refresh? There's no better time to try it out.

Enjoy!

Pokés: Alola Update

Hello trainers! How is your hunt coming along? You might already have heard of the region of Alola, and all of the new Pokémon that can be found there. Well, I'm glad to announce they finally made it to this virtual space!

With today's update, you can now start finding and catching the new Pokémon found in Alola, including the varieties of the ones you know, love, and maybe even own already! Keep your eyes peeled for the newcomers, and good luck catching them all!

Safari 13 and New XKit

Today, Apple began rolling out version 13 of Safari which removes support for non-app extensions, including XKit. Unfortunately, we have not been able to complete porting New XKit to an app extension in time. We are working on rewriting the Safari support code as a native app extension but it’s a bit difficult since Apple chose to invent their own ecosystem instead of supporting the growing industry standard of WebExtensions.

During our repeated attempts to figure out the intricacies of Apple’s harebrained API and extension structure we recommend that you use New XKit on another browser. You can also try using the workaround detailed in this post: http://osxdaily.com/2019/02/08/bypass-safari-no-longer-supports-unsafe-extension-error-mac/ with the .safariextz file from https://github.com/new-xkit/XKit/releases/latest but people have reported mixed results.
