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.

God bless you. Very good addon. Храни тебя Господь. Расширение просто сказка. Отсортировал все.

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.

Working quite well here with 20,052 bookmarks (no, that's not a typo). It takes a little while to sort (under 30 seconds), but has generally functioned as expected.

In the past, there have been conflicts with Firefox Sync and manually sorting, but I think the new bookmark sync backend (Mozilla bugzilla #1587357) has addressed that since Firefox 70.

Works quite well, and Eric gave quick support. Excellent!

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

Exclusion options don't seem to work properly, so it aggressively sorts folders you don't want sorted. It also sorted incorrectly at first until it was prompted to do so again.

This add-on is fantastic. I was hesitant because some of the reviews were bad. However, if you look you'll see that the bad reviews are from years ago. The majority of positive reviews are recent.

I'm also glad this add-on is open source!

Really good extension, pls add sort by tag as an option

Just downloaded this. Couldn't get firefox sort to work. Put it in auto and everything is now sorted perfectly. Shouldn't have to use an add on when firefox has a sort button. They need to fix. Very happy now!

Tried tweaking the settings a few times and it never sorted anything.

I have 21 megabytes of bookmarks (.json file). This addon sorts them in a minute and a half. The "Sort Bookmarks" addon sorts them in 10 seconds (like the old SortPlaces addon did). So I now use the "Sort Bookmarks" addon.

This thing SERIOUSLY lacking sorting by tags.
