FMHY SafeLink Guard 0.5.5 – Mini Changelog

This release introduces a 1-week cache for safe/unsafe domain lists, cutting down on constant refetching and ensuring better offline support. A new “Force Update” command allows power users to manually clear outdated data and fetch fresh lists on demand. Trusted domains now skip highlighting their own internal links, making navigation smoother on reputable sites. Tampermonkey’s storage is used extensively, boosting reliability between sessions. Users also gain an option to download all cached lists as JSON for easy backups, while improved logging clarifies what data is loaded from cache vs. newly fetched. Overall, 0.5.5 refines caching efficiency, expands user customization, and tidies up code for a more robust experience.

Changelog

Version 0.5.4

This update adds color customization, letting users choose the highlight colors for trusted and untrusted links. It also prevents the script from running on FMHY’s own domains to avoid unnecessary processing and self-flagging. A bug was fixed where custom colors were sometimes ignored after page updates. The settings panel was improved to include color pickers for easier customization. Overall, this release focuses on user customization, performance, and reliability.

Changelog

Version 0.5.3

Improvements

• Added detailed error logging to the console if fetching the trusted or unsafe site lists fails. Errors now show the failing URL and full response object.
• Added a console log summary showing how many safe and unsafe domains were successfully loaded from FMHY.

These changes improve transparency and make troubleshooting easier if FMHY's lists ever go down or change format.

Changelog - Version 0.5.1

List Source Change

Switched to FMHY's sitelist.txt instead of filterlist.txt. Previously, the script used filterlist.txt, which was originally intended for uBlock Origin. This has now been replaced with sitelist.txt, a dedicated plain-text list of unsafe or scammy domains maintained by FMHY for broader compatibility.

Simpler Parsing Logic

The parsing code was simplified because sitelist.txt is a clean list of domains (one per line), unlike the old uBlock-style filterlist that used || and ^ syntax.

Internal Improvements

List-fetching and parsing logic have been updated to match the new format. The overall behavior, showing one warning per domain per page, remains the same as version 0.4.1.

Why this matters

The old filterlist.txt was designed for uBlock Origin and similar adblockers, meaning it used syntaxes that are unnecessary for a userscript. The new sitelist.txt is cleaner, making it a better fit for this type of script.

FMHY SafeLink Guard v0.4.1 – Changelog

Compared to previous 0.3.x versions

• 
  “One-Warning-Per-Domain” Behavior:
  Introduced a new flaggedDomains set. Once the script flags a domain for the first time, it won’t issue another warning for the same domain on the same page. This prevents duplicate warnings on multiple links sharing that domain.
  
• 
  Domain Normalization:
  Added a new function normalizeDomain(hostname) to remove www. and convert the hostname to lowercase. This ensures consistent comparisons and eliminates minor mismatches in domain strings.
  
• 
  Minor Code Restructuring:
  Moved the “unsafe” logic into markLinksIn(), combined with the new flaggedDomains checks. The rest of the script—fetching the filterlist, applying user additions and removals, etc.—remains largely the same.
  
• 
  Version Bump:
  Updated the @version metadata to 0.5.0 to reflect these functional improvements.
  

FMHY SafeLink Guard v0.3.0 – Changelog

• Selective Scanning: The script now only scans newly inserted elements using the MutationObserver, rather than rescanning the entire DOM each time.
• Processed Link Tracking: Introduced a WeakSet to track links already flagged, ensuring they aren’t re-marked.
• Faster Domain Checks: Moved unsafe domains into a Set for more efficient lookups.
• Maintenance & Code Clean-Up: Reorganized functions and improved logging for clarity.
• General Performance Enhancements: Reduced CPU load on dynamic pages thanks to the above optimizations.
