As I first discovered today from the massive surge of people reblogging my previous update posts, the shitty new layout is now universal despite widespread protest, since us existing users are now apparently backseat to a Tumblr’s hypothetical endless stream of high-revenue new users who are allergic to using social media sites that don’t look like every other site. Well, thankfully at least for the time being, reverting the update via userscript is still as easy as ever!
Version 3.3.0 even fixes the new server-side bug where avatars next to posts disappear, because apparently I spend more time reviewing my commits than a multimillion dollar social media platform.
Installation Guide:
A userscript extension is required to run the script. Currently, the only tested extensions are Tampermonkey and Violentmonkey, but you might have still have luck with a different extension if you already use it.
Once you have the userscript extension installed, simply click this link to open the install page. This also works for updating, but make sure the version listed near the top is up to date, since it only fetches the script from GitHub every so often.
