If you mean websites (like this one for example) I put them in Favourites. You should see a Favourites button in your tool bar at the top. Right click and it will say 'add to favourites'. Do that for each site (while you have it open) that you want to access quickly. Totally non-techie answer but it works for me.
just right click somewhere on the page you want a box should appear -
select *bookmark this page* 5th option
it should then appear when you select Bookmarks (at the top left of page)
It should be the lowest entry - click on it & it should load page required.
