Some ways to try to revert it (some have already been mentioned)
👉 Go to this page and check if you’re able to opt out of the “Redesigned Watch Page” (source)
👉 Install a userscript addon like Violentmonkey, and then use a script like Classic Youtube Layout (which is based on this script which was outdated in regards to the related videos sidebar)
- If you get an error about the
@matchline of the script then click onallow editsand change it from*.youtube.com/*to*://*.youtube.com/*, or install the script as it is and then put*://*.youtube.com/*in the “@match rules” line in the settings tab of the script - There’s also this script that you would need to add its code manually to the userscript addon by clicking on the new script icon (see the author’s post for more details)
👉 Use uBlock Origin filters like these or these
- Note that
youtube.com##+js(set, yt.config_.EXPERIMENT_FLAGS.kevlar_watch_grid, false)should be enough to change the UI back for the most part
👉 Use this userscript and Stylus style
👉 The addon Enhancer for YouTube (Firefox / Chrome) also reverts the UI, at least partially
👉 (might only work some times) Use the addon CustomTube - Firefox / Chrome (the default UI is from 2017 but you can choose 2021 in the settings. It’s not exactly like the one from 2023 but it’s close enough)
- note that it removes some buttons like Join by default so go over the settings if relevant
If you also want to change the number of videos per row in the subscription page and channels’ videos page, then you can add this uBlock Origin code to the “My filters” tab (at the end click “Apply changes”, or Ctrl+S) (this is for 6 items per row but you can change the number in the first 2 line as needed) (source 1 / source 2)

Does it work for you when the word is at the start or end of the title?
I found that the previous/next post’s text interferes with that because it doesn’t recognize a line break between them (at least in my testing)
