Greasy Fork

1. Batch Processing: Posts are processed in batches using requestIdleCallback.
2. Debounced Updates: MutationObserver events are debounced to reduce redundant processing.
3. Optimized Blocklist: A Set is used for blocklistSet for faster lookups.
4. CSS Injection: Styles are injected only once.
5. Error Handling: Added error handling for GM.getValue and GM.setValue.
6. Code Modularization: Split logic into smaller, reusable functions like hidePost and processPostsBatch.
7. Modern JavaScript: Used let, const, optional chaining (?.), and nullish coalescing (??)

Updated the description

Counter Updates

-Removed requestAnimationFrame wrapper around counter updates
-Moved counter increment outside async operations
-Added requestIdleCallback for non-blocking updates
-Implemented batch processing with 16ms debounce timer

Performance Improvements

-Increased batch size from 5 to 10 posts
-Added pending updates tracking
-Implemented periodic cleanup of counter updates
-Aligned updates with browser refresh rate

These changes make the filtered post counter more responsive and reduce UI freezing when processing large numbers of posts

Optimizations

Optimized for Firefox-based browsers (which shouldn't affect Chromium-based browsers)

I renamed the userscript to better-reflect its functionality and added the ability to filter specific subreddits out of the feeds such as r/all

1. Enhanced Keyword Matching: The script now automatically filters out common plural forms of your specified keywords

2. Updated configuration menu

3. Updated userscript icon

Bugfix

1. Performance Optimizations:
- Added cached selectors (POST_SELECTORS and CONTENT_SELECTORS) to reduce repeated DOM queries
- Implemented debouncing for post processing to prevent excessive function calls
- Added a process queue system using requestIdleCallback for better CPU utilization

2. Preloading Feature:
- Added preloadPosts() function to fetch and parse the next page of content before it's needed
- Implemented error handling for the preloading functionality

3. Memory Management:
- Added a cleanup interval that removes references to posts no longer in the DOM
- Improved the WeakSet implementation for better garbage collection

4. Code Structure:
- Reorganized the code into more logical sections
- Added better error handling throughout the script
- Improved the initialization process with better state management

Added @icon to the userscript

Changed the name

Optamized the blocking logic and fixed the Configure button
