7.10 Set Extension Update Interval Time Checks

Information

This feature sets the amount of time the system waits between checking for updates.

Rationale:

Setting a specific amount of time between automatically checking for updates mitigates the risk that a system will left vulnerable to known risks for an extended period of time.

Impact:

None - This is the default behavior.

Solution

To establish the recommended configuration, set extensions.update.interval to 86400:

Type about:config in the address bar

Type extensions.update.interval in the filter

Ensure the setting is set as prescribed.

OR

Open the mozilla.cfg file in the installation directory with a text editor

Add the following lines to mozilla.cfg:

lockPref('extensions.update.interval', 86400);

Note: Configuring this setting to a value less than 86400 also conforms with this benchmark.

Default Value:

86400
