I can't think of a single browser I use that doesn't have the bookmarks on the left side. It makes it easier to open nested bookmark folders.
If the bookmarks are not in an order that you like, then just move them.
There's several methods to do that (at least in Safari)
You can just click and drag any item to another position on the bookmark bar. OR
click on the Show Sidebar icon in the bookmarks bar (or Show Sidebar from the View menu, and drag the items to positions that you like. OR
click on Show Bookmarks from the Bookmarks menu, and edit the bookmarks and their location to your heart's content.
You can do the same with any of the folders - move them to the left end, if that's where you want them.
