Kourou, we have a problem ... EDIT: fixed with ver. 1.4 (sandbox at this time) Rated 5 out of 5 stars

EDIT: Version 1.4 fixed 1.3 issue -- Thanks to the developer for this x-ttra fast update. We remain on orbit :)
---
A problem with ASB 1.3 only.No icons, no link in Firefox menus, unable to run therefore.Could be related to incompatibility with another add-on since other users here have not called the space center to mention this incident :)Hope you copy me on the ground. Roger.

This review is for a previous version of the add-on (1.3). 

Version 1.2 (sandbox) is like day after night ! Rated 5 out of 5 stars

'Auto-Sort Bookmarks' version 1.2 abolishes de facto my previous scoring (for the best !). I was a bit harsh (combination of private life and the legitimate opportunity to be nasty nevertheless). Anyway, version 1.2 (sandbox!) works nicely, both automatic and manual, respects folders and separators : the best of two worlds, one, automatic and forget it, the other, manual, for when we like to have visual access to last boorkmark(s). It's very fast and up to now have encountered no problem. 5 stars.

This review is for a previous version of the add-on (1.1). 

Ignores the separators ... Rated 2 out of 5 stars

Separators is one of the best things of Firefox bookmarks management, and of course Firefox, when sorting, handles separators as it should.
How on Earth could anyone possibly use such a sorting scheme as that proposed by this add-on ? I don't mean to be nasty but, frankly, I think the author should reconsider the very substance of his approach before coding.
