HI legendmc, I just tested this from the Bookmarks menu from the top menu on my Mac. Any folder opens to the left first then sub menus to the right. Logically it could be a realestate issue.

But first, can you please see if you can reproduce this in Diagnose Firefox issues using Troubleshoot Mode ?

I went into safe mode and tried it again. It still has the same problem, but only with two subfolders, I eliminated them and then reintroduced them... Same issue. When using the top bookmark menu, the bookmarks open to the RIGHT, and then to the LEFT... Opposite from yours. Problem still remains... only on the two subfolders. I have tried others and they work fine. Thank you! Matt

Yup, I just opened the menu on a larger screen. It does open on the right first then the left.

So it is just two specific subfolders that are doing this, but new ones do not. I am wondering if they were corrupt in the backup, is it possible to make a copy of one of the ones that are not working?

These two folders have done this ever since I created them. I have deleted all bookmarks in Firefox and then reintroduced them all... Problem still persisted. I took the bookmarks out of the subfolders and deleted the subfolders. Bookmarks worked. I recreated the folders and added the bookmarks in, the problem still persisted. I have a 27" iMac. The bookmarks open to the right, then the subfolders, right again. But they function because of the extra real estate. On this notebook, they open right, then left... With the exception of these two subfolders. It is a conundrum! This issue actually drove me back to Safari. I like Firefox, but this is crazy! And, thanks for your help!

You can check for problems with the places.sqlite database file in the Firefox profile folder.
