Use uninstall to remove managed browser runtimes from the Extension.js cache. This only removes browsers that Extension.js installed in its managed cache root. It does not touch system Chrome, system Edge, or any browser installed outside that cache.

​
When to use uninstall

  • You want to reclaim disk space from managed browsers you no longer need.
  • You are resetting a managed browser install to force a fresh download on next install.
  • You are cleaning up continuous integration (CI) caches or switching browser targets.

​
Canonical usage

For a single browser, use the positional form:
Use --all to remove every managed browser target.

Arguments and flags

Examples

​
Remove managed Chrome for Testing

​
Remove all managed browsers

​
Show the managed uninstall path for Firefox

​
Best practices

  • Use --all in CI teardown to clean up managed browsers after test runs.
  • Use --where first to confirm what will be removed before scripting bulk uninstalls.
  • uninstall is safe for system browsers; it only removes Extension.js-managed cache folders.

​
Behavior notes

  • If you set EXT_BROWSERS_CACHE_DIR, uninstall uses that custom cache root.
