Samsung T580?

I have SM.T580 tablet, and browsing internet or going into email a tab appears at top of the page. this allows quick access when pressed as I found which many, I don't want. examples of tabs are email, Wickes, B&Q etc. there are lots and its a pain pressing x on each to remove.
QUESTION. From 80yrs old pc illiterate auld git :

How to delete these tabs in one easy move ?

I thought there were only a few until I started to delete them.
Many thanks in advance.
