Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\Tor Browser\Browser\tor-browser-telemetry.exe
Warning
Telemetry may be optional
Tor Browser uses telemetry only if opted-in; background activity is minimal
Can I Disable?
✔ YES
You can disable by turning telemetry off in about:config or equivalent privacy settings
What is tor-browser-telemetry.exe?
tor-browser-telemetry.exe is a component of the Tor Browser suite that collects anonymized usage data to help The Tor Project improve privacy features, performance, and user experience. It operates under opt-in controls, minimizes data collection, and respects user privacy. It runs within the browser's sandboxed process environment to reduce risk.
Telemetry collects anonymized feature usage, crash data, and performance metrics while avoiding personal data. Data is batched and encrypted before transfer, and never includes URLs or browser history unless explicitly opted in.
Quick Fact: Tor Browser emphasizes privacy; telemetry is only active when the user opts in, and data is designed to be non-identifying.
Types of Telemetry Processes
- Telemetry Collector: Gathers anonymized usage and performance metrics when telemetry is enabled
- Data Preparer: Aggregates data in a privacy-preserving way before sending
- Data Sender: Encrypts and uploads data to Tor telemetry service
Is tor-browser-telemetry Safe?
Yes, tor-browser-telemetry is safe when it comes from The Tor Project and is used according to opt-in privacy controls.
Is tor-browser-telemetry.exe a Virus or Malware?
The real tor-browser-telemetry.exe is NOT a virus. Malware may impersonate names; verify the path and signature.
How to Tell if tor-browser-telemetry.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Tor Browser\Browser\tor-browser-telemetry.exe or a tor-browser directory provided by The Tor Project. Any other path is suspicious.
- Digital Signature:: Right-click the executable in Explorer → Properties → Digital Signatures. Should show a signer like "The Tor Project".
- Resource Usage:: Normal telemetry activity uses minimal CPU and memory when enabled. Unusually high usage with no UI activity is suspicious.
- Behavior:: Telemetry should only operate when the browser is running and telemetry is enabled. Persistent background activity when the browser is closed may indicate malware.
Red Flags: If tor-browser-telemetry.exe is located in unusual folders (Temp, AppData, System32), runs when Tor Browser is closed, has no valid signature, or uses excessive resources constantly, scan with a trusted antivirus. Look for similarly named files.
Why Is tor-browser-telemetry.exe Running on My PC?
Tor Browser telemetry runs to collect anonymized usage data when enabled. It may also participate in background checks or health reports depending on user settings and build configuration.
Reasons it's running:
- Opt-In Telemetry: You have enabled telemetry in Tor Browser's privacy settings, triggering data collection
- Background Health Reports: Periodic health/diagnostic reports may run to assess browser stability
- Startup Initialization: Tor Browser startup may initialize telemetry components to prepare for data handling
- Feature Usage Analytics: Telemetry may briefly run to log feature usage for research and quality improvements
- Automated Error Reporting: If a crash occurs, a privacy-preserving report can be generated and queued for upload
Can I Disable or Remove tor-browser-telemetry.exe?
Yes, you can disable tor-browser-telemetry. It will not affect Tor Browser functionality, and you can disable data collection entirely if you prefer no telemetry.
How to Stop tor-browser-telemetry
- Open About: Config in Tor Browser: type about:config in the address bar and press Enter
- Disable Telemetry Preference: Set toolkit.telemetry.enabled to false (if present in Tor/Firefox-based config)
- Disable Health Reporting: Set datareporting.healthreport.uploadEnabled to false
- Disable Telemetry Server: Set toolkit.telemetry.server to an empty string or disable any telemetry server endpoint
- Restart Tor Browser: Close and reopen the browser to apply changes
How to Uninstall Tor Browser Telemetry
- ✔ Delete the Tor Browser folder from the installation directory (e.g., C:\Program Files\Tor Browser or your portable Tor Browser directory)
- ✔ If you installed via an installer, run the installer again and choose modify/uninstall, then deselect telemetry components if available
- ✔ Alternatively, remove the entireTor Browser bundle to ensure all telemetry components are removed
- ✔ Check for leftover configuration files in the profile or appdata folders and delete them if you want a clean removal
Common Problems: Telemetry-Related Issues
If tor-browser-telemetry.exe has issues, try the following common scenarios and solutions.
Common Causes & Solutions
- Telemetry Disabled but Process Runs: Verify settings in about:config and restart Tor Browser to ensure telemetry is truly disabled
- High CPU or Memory While Idle: Ensure telemetry is disabled or limit data collection by toggling preferences; check for conflicting extensions
- Data Not Uploading: Check network connectivity and ensure data reporting endpoints are reachable; verify that uploadEnabled is true if you intend to send data
- Unknown Process Location: Confirm tor-browser-telemetry.exe path under the Tor Browser installation; replace or reinstall if path differs
- Privacy Concern Over Data Collected: Disable telemetry or switch to opt-out mode; review privacy settings and data types collected
- Telemetry Stopped After Update: Clear caches, reapply telemetry settings in about:config, and restart the browser after updates
Quick Fixes:
1. Quick Fixes:
2. 1. Open Tor Browser and navigate to about:config
3. Set toolkit.telemetry.enabled to false
4. Set datareporting.healthreport.uploadEnabled to false
5. Restart Tor Browser to apply changes
6. If desired, delete the tor-browser-telemetry.exe file from the installation folder
Frequently Asked Questions
Is tor-browser-telemetry safe?
Yes. Tor Browser telemetry is designed to collect anonymized usage data and operates under opt-in privacy controls. It does not collect sensitive browsing history by default.
What data does tor-browser-telemetry collect?
It collects aggregated feature usage, performance metrics, and crash reports in an anonymized form. No URLs or personal content are collected unless you opt in to broader data collection.
Can I disable tor-browser-telemetry permanently?
Yes. Use about:config to disable telemetry-related preferences and restart the browser. This will stop data collection.
Where is telemetry data stored and can I delete it?
Telemetry data is stored in the Tor Browser profile folder as anonymized logs. You can delete the data by removing the profile contents or uninstalling the browser, but note you may lose related settings.
Does telemetry affect my privacy or anonymity?
Telemetry is designed to minimize privacy impact, focusing on non-identifying usage data. It should not undermine Tor’s anonymity if disabled or configured properly.
How do I know tor-browser-telemetry.exe is legitimate?
Verify the executable path is within the official Tor Browser directory and that a signer matches "The Tor Project". Avoid unknown folders and ensure the file is digitally signed.
