# This extension may have been corrupted

Occasionally, the Devolutions Password Manager browser extension may become corrupted in your browser. The error message is usually: ***This extension may have been corrupted***.

#### Windows roaming user profile

Using a [Windows roaming user profile](https://learn.microsoft.com/en-us/windows-server/storage/folder-redirection/deploy-roaming-user-profiles) may lead to corruption issues in the Devolutions Password Manager browser extension. This typically occurs in environments where large user profiles are synchronized and copied during log-on or log-off. As the profile size increases, the time required to complete these operations also increases.

1. Prevent the following folder from being included in the roaming profile: `%LocalAppData%\Google\Chrome\User Data`.
2. Use the `UserDataFolderMode` and `UserDataFolderPath` properties to configure a custom, persistent user data folder. These properties can be applied in:
   * Classic open browser activity
   * Modern use application/Browser activity

#### Devolutions Password Manager browser extension corrupted from damaged or misconfigured browser user profile

Devolutions Password Manager browser extension may become corrupted if the browser’s user profile is damaged or misconfigured.

1. To avoid interference, exclude the following path from the anti-virus allowlist: `%LocalAppData%\Google\Chrome\User Data`.
2. For environments using roaming profiles or redirected folders, consider specifying a different location for the browser user data folder to avoid conflicts.
