I'm using Firefox 47.0 on Fedora (64-bit GNU/Linux) with GNOME shell, and on Windows 10 (64-bit). I also have Firefox Sync on an Android tablet, but I don't do as much web browsing on my tablet, so I haven't needed to look at the bookmarks there...
On Fedora, the bookmarks in the Firefox bookmarks toolbar rearrange themselves. The bookmarks in one folder shift from the bottom to the top, and some bookmarks in the toolbar shift from left to right. I arrange my bookmarks by loose priority, so this annoying. Whenever I notice the bookmarks being out of order, I drag them back to where they were, but they always move themselves again later. This has been an ongoing issue for a couple months; I've only seriously attempted to troubleshoot the issue over the past week or so, and I'm not having any luck.
I don't think I've ever noticed the bookmarks moving themselves in the middle of a session, so I believe it's actually happening when I close or launch Firefox. However, reproducing this issue has been tricky, since the bookmarks do not *always* shuffle themselves every time I launch Firefox. Depending on how often I open/close the application, I may notice the bookmarks moving themselves once every other day, or a couple times in a single day.
This may be a separate issue, but I noticed it around the same time: On Windows 10, my bookmarks do not sync at all. There three or four bookmarks in the toolbar, but these do not get updated when I change them on my Linux machine, and none of the other bookmarks have synced to the Windows machine.
Things that I've already tried
I've tried reverting my bookmarks to a recent automatic backup (Library > Import and Backup > Restore). No change.
I've tried disabling all addons. No change.
I tried refreshing Firefox, to "reset to factory defaults". No change.
I tried deleting the file `xulstore.json` in my Firefox profile. No change.
I tried installing and running the Places Maintenance extension. I didn't entirely understand all the text output it generated while running, but I don't think it found any real errors. Anyway, no change.
I tried backing up my exports to a JSON file, then closing Firefox, then deleting the places.sqlite file, then restarting Firefox, and importing the bookmarks JSON file. No change.
Bookmarks still rearrange themselves on Linux and do not sync at all on Windows :(
