Feed browser shows feeds subscribed by other users of the instance which
are not marked as private, have no login information entered and are not
already subscribed by the user.

### Data cache, applies since 1.2.31

To minimize time spent by generating the feeds index, Feed Browser
uses a cache of subscription information. This cache can be generated
as follows:

-   Update daemon handles feed browser cache automatically. If you are
    using update daemon, you don’t have to do anything else.
-   Manually by running <code>update.php —feedbrowser</code>
