Ungoogled Chromium Not Working Fix - Ungoogled Chromium

Ungoogled Chromium not working can be resolved by clearing the user profile cache, reinstalling the browser, or adjusting system permissions on your Windows or Linux machine.

Clear Cache and Profile Data

The most common cause of crashes occurs when profile corruption accumulates over time. Navigate to the installation directory and delete the "Default" folder located in the User Data path. On Windows, this path is typically `C:\Users\[YourUsername]\AppData\Local\Ungoogled Chromium\User Data`. On Linux, check `~/.config/ungoogled-chromium/`.

Restart Ungoogled Chromium after removing this folder. The browser will reconstruct default settings automatically.

Alternatively, access Settings > Privacy and Security > Clear Browsing Data and select "All time" before removing cached files and cookies. This troubleshoot method resolves most error messages without complete reinstallation.

Reinstall and Update

Version 144.0.7559.132 may encounter compatibility issues on older systems. Download the latest release directly from the official GitHub repository (26,153 stars) rather than third-party sources. Remove the existing installation completely through your system's Add/Remove Programs utility before downloading fresh.

For Windows users: uninstall via Control Panel, restart your computer, then install the new version. For Linux: use `sudo apt remove ungoogled-chromium` followed by reinstallation through your distribution's package manager.

Check System Permissions

Permission restrictions frequently cause Ungoogled Chromium not working on multi-user systems. Right-click the application executable and select "Run as Administrator" (Windows) to grant necessary access. On Linux, verify your user belongs to the correct groups: `groups $USER` in terminal.

Disable any conflicting antivirus real-time scanning temporarily to test if security software blocks the browser's operation. Some firewalls mistakenly flag privacy-focused applications.

Recommendation: Start with cache clearing—this solves approximately 70% of reported issues. If the error persists after these steps, perform a fresh installation of version 144.0.7559.132 from the official source.
