FF 56.0.2 and Xmarks 4.5.0.4 cannot download bookmarks

After upgrading both FF to 56.0.2 and Xmarks to 4.5.0.4, and both on Win7 and Mac OS X, I found both FFs stopped to work anymore.

1. The first run of my FF on Win7 asked to "merge" bookmarks , and created lots of redundant empty folders.

2. I removed them and re-sync them again in Chromes on both Win7 and Mac OS X.

3. Then my FF on Win7 complained to have sync problems.

4. I tried to download bookmarks directly from the server, the usual way to fix issues.

5. Now the full download simply failed. All bookmarks on FF were cleaned up but I could not get any booksmarks ever since.

I have tried every suggestion but there is no way to fix this new version.

I finally solved this issue... by downgrading and sticking to FF 52 ESR and using Xmarks 4.4.1 instead...

Hope when next FF ESR is released this will be solved.
