It's not "Sort Bookmarks", it's "Sort Bookmarks BY FOLDER".
So basically, this does nothing more than what Firefox already does by default.
Useless.

Works well. Most reliable way to have settings per folder is to have bookmarks sidebar open and right click on a folder, then select 'Sort this folder'. In fact this seems to be the only way to set unique settings for 'Other Bookmarks' folder. Using Firefox.

hey man, I'm trying to sort a folder in the firefox bookmark manager (separated window). when I right click the folder and click "sort this folder", the add-on dialog open and close immediately, and I can't do anything.

It should have the option to sort by visit count.

Not able to Reset After Sort

This one actually works! Just be sure to click on its toolbar button and enable "always keep sorted". For whatever reason the most important option isn't shown in the add-on's options dialog.

I tested a few other bookmark-sort add-ins, but this one ticks all the boxes. You can sort bookmark maps and bookmarks separately, even exclude some maps/bookmarks. Perfect.

Najlepszy!

Great sorting by letters. However, I want it to have sorting by Chinese pinyin. It'd be great to have that.
