I can't delete bookmarks by the traditional means since it freezes FF.

I need to mass delete these bookmarks AND I need to purge my new FF Sync account. How can I do that? The old sync allowed you to purch bookmarks in the cloud.

The large amount of bookmarks are all "Mozilla Firefox" folders. It's impossible to delete them all.

I use sync wth 3 computers (2 offices, 1 noteboook), 3 iOS and 1 Android device. It's a nightmare!

This has helped a lot with a lot more resources. The add on I ultimately used successfully was the SQLite Manager. I went in and did a mass delete of all the duplicate bookmarks. There were over 10000 of them that caused problems with the freezing and synch. I could not use the "Show your bookmarks" button on FF because of the large number.

All of the duplicated bookmarks were "Mozilla Support" folders. I think there is a larger problem with sync. I have 3 computers and 4 devices that sync and I suspect that when there are updates, whether it's FF, Windows OS updates, re-installs or anything, the Places file grows over time. This problem became most apparent when moving to the new sync. Due to geography I couldn't put all my devices on the new sync simultaneously. Maybe it's something about the old and new sync when devices are split? Very strange.
