You can arrange your favourites tabs into any order that you want to on your facebook timeline with the only exceptions being that you can’t move the friends or photos tab, these will always stay in position.
To move your tabs you have to make sure they are all displayed by selecting the arrow to the right of your tabs so all your favourites are displayed
Once you have done this hover the mouse over the top right of the favourite you want to move.
You will be given the choice from all the favourite tabs you have, select which one you want to swap it with
This will happen automatically and there is no need to save or refresh the page
