If you are tired of a cluttered YouTube Subscriptions feed filled with videos you don't want to watch, YouTube Subscriptions Filter allows you to curate your feed with precision. Unlike other filters that leave annoying blank white spaces in your grid or only hide watched videos, this extension completely collapses all hidden elements you decide to filter, ensuring your next videos slide up seamlessly to fill the gaps.

Core Features

"Watched Video" Hiding: Automatically clean up your feed by hiding videos you have already seen. You set the threshold (e.g., automatically hide videos watched past 90%), and the extension reads YouTube's native progress bar to do the rest.
Fade Mode vs. Hide Mode: Don't want videos to completely vanish? Enable Fade Mode to turn filtered videos grayscale and dim them to 20% opacity. This visually deprioritizes content while keeping it clickable if you change your mind.
Advanced Channel Exceptions: Set conditional filters for specific creators. You can choose to Keep ONLY videos that contain a specific keyword from a channel, or Hide ONLY specific topics from a channel you otherwise love.
Global Channel & Collab Blocking: Instantly banish all videos from a specific creator. This powerful filter also catches multi-channel collaborations, hiding the video even if the blocked creator is just listed as a guest.
Past Live Stream (VOD) Blocker: Automatically hide previously streamed videos so your feed is strictly standard uploads. Includes advanced Whitelist and Blacklist modes so you can keep VODs from your favorite streamers while blocking the rest.
Keywords & Advanced Regex: Block any video title containing specific keywords or emojis. For power users, the Advanced Regex input allows you to catch complex title structures, spammy formatting, or specific numbering conventions.

Seamless Integration & Control

Custom Scope: By default, filters apply only to your Subscriptions page. With one click, you can unleash your rules globally, cleaning up the YouTube Home page, Search results, and Recommended sidebars.
Firefox Cloud Sync & Local Backups: Never lose your complex rulesets. Manually push and pull your settings to your encrypted Firefox account to sync them across your computers, or export them to a local JSON file for safekeeping.
