3. Visit the Moodle admin page to complete the installation.

Usage

2. Edit the settings of the activity or resource you want to restrict.
3. In the "Restrict access" section, click "Add restriction...".
4. Select "User agent".
5. Enter the user agent regex you want to restrict access to, without delimiters, e.g. ^.*(Chrome|Firefox).*$.

Example usage to check for minimal navigator version

Use case: check and dispay a message to the user on the course page of the user is not at least on Chrome 120, Firefox 130, or Safari 18.

1. Create a Label containing the test "Your browser version is unsupported." (or equivalent message).
2. Add a "User agent" access restriction rule with the following RegExp: ^.*(Firefox.*13\d|Chrome.*12\d|18\..*Safari).*$
3. Chose the must not option instead of the must option to invert the access condition.
4. Click the eye icon next to the access rule to make it that the Label is not displayed when the condition is met.

The effect is that the label containing the warning is only displayed if the client browser versoin does not match the criterion.
