This extension works roughly well. However, I do not recommend using auto-sorting if you want to sort only bookmarks in some folders, because every time I changed the settings, the target folder settings were reset. For now, I check the folder settings and perform the sorting manually.

This almost works for what I wanted, but then fails in the end.

While nice that everything was sorted as promised the second option mentioned in the addon description was the one that made me install it.
As in, I'm someone with a lot of bookmarks from stuff I am reading it is common to have duplicate bookmarks with only the chapter number differing. I could sort by titles to fix this, but I like the bookmarks sorted by date to know which are the oldest. This addon in theory would allow me to sort by date, and then if two similar bookmarks found they would be paired. But this is not the case. The second sorting option has no effect no matter which option is chosen.

Sorts well, but after you sort, the folder configuration resets. This makes the auto-sorting useless for me.

This thing SERIOUSLY lacking sorting by tags.

This is an excellent add-on with one big problem. It ignores separators when sorting.

Thanks so much for adding the Exclude Folder option! Been waiting for that before I installed the extension. Now that I have installed the extension, the Options page now is opening up in a new tab with EVERY launch of Firefox (latest version, BTW) and the Options settings also are being reverted back to their default settings! These are major issues that must be fixed before I can re enable the extension.
