Facebook Comment Sorter - Auto Sort Comments + View Replies
This userscript forces Facebook comments to always show "All Comments" or "Newest" instead of the annoying default "Most Relevant". It works on the latest Facebook interface and supports many languages.
🆕 NEW in v2.1: Now automatically expands "View X replies" buttons so you don't have to click them manually! Perfect for reading entire comment threads without the hassle.

🛠️ Customization
Open the script and edit the CONFIG section at the top:
const CONFIG = {
sortPreference: "all", // "newest" or "all" - your choice
debug: true, // Console logging for nerds
expandReplies: true, // Auto-expand reply buttons (the good stuff!)
replyExpandDelay: 1000, // Delay between expansions in milliseconds
viewportOnly: true // Only expand visible replies (recommended)
};
Quick Setup Examples:
- Want newest comments first? Change
sortPreference: "newest"
- Don't want auto reply expansion? Set
expandReplies: false
- Slow internet? Increase
replyExpandDelay: 2000 (2 seconds)
- Want to expand ALL replies even off-screen? Set
viewportOnly: false
📖 How It Works
This script is pretty sophisticated and uses multiple attack vectors to make sure Facebook can't override your preferences:
Comment Sorting Magic:
- UI Method: Identifies and clicks the right sorting option in Facebook's dropdown menu
- API Interception: Intercepts and modifies network requests to add sorting parameters server-side
- Persistent Override: Keeps enforcing your choice even when Facebook tries to be "smart"
Reply Expansion Intelligence:
- Smart Pattern Detection: Recognizes reply buttons in 12+ languages using advanced text matching
- Detects: "View 5 replies", "5 balasan", "Ver 5 respuestas", "5 réponses", etc.
- Avoids: "Hide replies", "Load more comments", collapse buttons
- Viewport Awareness: Only processes reply buttons you can actually see (configurable)
- Memory Management: Remembers which buttons it already clicked to avoid loops
- Scroll Preservation: Maintains your exact reading position when content expands

🚨 Known Limitations & Warnings
- Reply expansion processes one button at a time to avoid overwhelming Facebook's servers and getting rate-limited
- Some Facebook A/B tests might temporarily affect functionality - this is normal, wait it out
- Very long comment threads (500+ replies) might require manual intervention due to Facebook's own limits
- Script might occasionally break parts of Facebook interface during major Facebook updates
- Mobile Facebook app not supported - this is for desktop/mobile web only
💡 Performance Tips & Best Practices
- Enable
viewportOnly to reduce processing overhead and save bandwidth
- Increase
replyExpandDelay on slower connections or if you notice Facebook throttling
- Disable
debug mode for daily use to reduce console noise
- Monitor browser performance - if Facebook gets sluggish, temporarily disable reply expansion
- Use "All Comments" over "Newest" if you want to see the full conversation context
- Refresh page if things get weird - Facebook's SPA sometimes needs a reset
⚠️ Final Warning
This script can sometimes break parts of the Facebook interface, especially during Facebook updates or when they're A/B testing new features. If anything looks off or stops working right, just disable the script temporarily.
Use at your own risk — you've been warned, but it's totally worth it for the convenience!
