You can also change the default browser here. If you configure iCab Mobile as the default browser, additional features are available, such as the option to save websites to the home screen.
The option Allow cross-site tracking allows you to reduce the strict privacy settings of iOS. Normally you should leave this option disabled to get the highest possible privacy. However, a few websites (such as some Microsoft business websites) cannot cope with this high level of privacy and by activating this option you can get these sites to cooperate.
The switch Delete session (current user) deletes all tabs of the currently logged in user. This can solve problems with crashing websites that would reload on startup.
Delete session (all users) deletes all tabs of all users.
The switch Delete settings (current user) reverts the settings of the currently logged-in user to the defaults. This can be useful if you have 'messed up' the settings and want to return to the default settings. However, this switch only affects the settings, i.e. bookmarks, filters, downloads and other user-defined data are retained.
Delete settings (all users) does the same for all user accounts.
