Hello mert_brenneman,

Would you do this please :

Press Ctrl + Shift + B - this will take you to the Library.

On the upper left side, click "Views" and choose "Sort".

At the bottom of the dropdown that appears you can choose
either "A > Z" or "Z > A".

Does that works for you ?

With all due respect for my colleague McCoy, using the Views > Sort menu in the Library window won't provide a permanent change to your Bookmarks. That menu item only does a temporary "view" of the selected sort order; once the Library window is closed the original order will prevail (or return).

To get a true Sort by Name order (or alpha-sort) in the Library use the left column or left panel and right-click on the Bookmarks Menu folder. Use the Sort by Name menu item in that contextual menu.

That will do an alpha-sort of the folders first, followed by the 'loose' bookmarks in their own alpha-sort order. And if you are using folders for organizing your bookmarks, the individual bookmarks in each folder won't be alpha-sorted. The "sort order" works folder-by-folder; no mass sort order is available. AND if you are using / adding Separators for your bookmarks, as I recall the sort order is limited to being between separators; a feature to allow for a partial sorting of bookmarks and/or folders of bookmarks - not well documented,but rather something that uses tend to stumble across.
