Firefox and Chrome cannot synchronize with each other, but if you use the same browser, you can synchronize. I use dropbox, Chinese environment, and bookmarks containing Chinese and other languages. I hope it can be fixed soon. This problem has been around for many years. I invited some people in the community to test, and they all had the same situation.

The idea is great, but it doesn't work for me. Push from Firefox works., but Chrome can't pull the bookmarks - neither from Google Drive nor from Dropbox.
