modcore Inspect is your proactive security scanner within modcore Extension Manager. It analyzes your installed extensions against an up-to-date database of known conflicts, deprecated extensions, and security risks - helping you identify problems before they cause browser crashes, performance issues, or security vulnerabilities.
Unlike passive security features, Inspect actively compares your extensions against a curated knowledge base maintained by modcore. It detects when you have multiple extensions fighting for control of the same web page features, flags extensions that are no longer maintained or have known security flaws, and identifies specific combinations that are known to cause problems.
When you first open Inspect, you'll see an introduction screen explaining the feature. Click Start Scan to begin your first analysis. The scan typically completes within seconds, examining all your installed extensions against the current database.
After the initial scan, Inspect remembers your results and displays them immediately when you return - provided the data is less than 24 hours old. After that window expires, you'll need to run a fresh scan to get current results.
Inspect organizes findings into clear categories:
Conflicting Extensions are groups of two or more active extensions that interfere with each other. Common examples include multiple ad blockers, overlapping privacy tools, or extensions that modify the same website elements. Each conflict shows:
The specific group name (like "Ad Blockers" or "VPN Extensions")
A description of why these extensions conflict
The risk level (Critical, High, Medium, or Low)
A recommended action explaining which to keep or how to resolve the conflict
Every conflicting extension in the group with version and ID information
Deprecated or Risky Extensions are individual extensions flagged for security or maintenance concerns. These might be abandoned by their developers, removed from the Chrome Web Store, or have known vulnerabilities. Each entry includes:
The specific reason for the flag (outdated, unmaintained, security risk, etc.)
The security risk level
Recommended alternatives when available - direct links to safer extensions that provide similar functionality
Ignored Extensions appear in a separate section showing extensions you've chosen to exclude from future scans. This is useful for advanced users who understand a particular conflict but want to keep the extensions anyway.
For every problematic extension, you have several options:
Disable immediately turns off an extension without uninstalling it. This is the fastest way to resolve conflicts - Inspect keeps the first extension in each conflict group active and offers to disable the others.
Ignore removes an extension from future scan results. Use this when you understand a warning but choose to accept the risk anyway. Ignored extensions move to their own section and won't appear in conflict or deprecated lists again unless you un-ignore them.
Details opens the extension's Chrome settings page for deeper investigation - viewing permissions, site access, or uninstalling completely.
Fix All is a powerful one-click solution that appears when you have multiple issues. It automatically disables all conflicting extensions except the first in each group, and disables all deprecated extensions. Inspect shows you a summary of exactly what will be changed before confirming, and you can always re-enable extensions manually later if needed.
Refresh Data fetches the latest conflict database from modcore's servers and re-scans your extensions. Use this when you install new extensions, enable previously disabled ones, or just want the most current security information.
Scan History tracks your recent analyses. Click the timestamp in the header (showing "Last scanned: [date]") to see a popover of your last five scans, including how many conflicts and deprecated extensions were found each time. This helps you spot trends - like if conflicts keep appearing after you thought you fixed them.
Settings let you customize Inspect's behavior:
Auto-scan on open: Automatically runs a fresh scan when you open Inspect if your cached data has expired
Show resolved issues: Keeps fixed issues visible in your history for reference
Cache duration: Adjust how long results remain valid (6, 12, 24, or 48 hours)
Clear all data: Removes all scan history, cached conflict data, and ignored extensions list
Every issue is color-coded by severity:
Critical (red) indicates severe conflicts or security risks that could compromise your browser stability or data safety. These demand immediate attention.
High (orange) represents significant conflicts or concerning security issues that likely impact performance or pose real risks.
Medium (yellow) covers moderate conflicts that may cause occasional issues or extensions with minor concerns.
Low (blue) is informational - minor conflicts or extensions with theoretical risks that probably won't affect daily use.
Inspect requires an internet connection to download the conflict database. This database is fetched from modcore's servers and cached locally on your computer. Your actual extension list and scan results never leave your device - modcore's servers don't see which extensions you have installed.

Scan results are stored locally using Chrome's storage API and automatically expire after your chosen cache duration (default 24 hours). No data persists in the cloud or syncs between devices.
Since Inspect needs to be connected to the GitHub API, Availability may vary depending on the region.
