Well done. Nice and easy. Saves a lot of manual work.

One and only real extension that does that job. Does it perfectly well. Does it in ALL folders and ALL sub-folders. And on top of all that, does it automatically.
Damn @*$%ing cool.

Thanks for developing and sharing that lovely piece of code.

very nice! I love it! I set it " Data Added" & Reverse Order

Funktioniert einwandfrei nachdem man alles richtig eingestellt hat.

As long as you are careful to select the correct folders and save your options after changing any settings, I have not had any issues with this addon. Works great, even the auto-sort feature. I currently have it set to arrange bookmarks in certain folders to automatically sort the most recently visited pages to the top of their folder list. Does exactly that.

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

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!

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!
