Not working in Chrome if you have many dials

I use the last version of Chrome, 52.0.2743.82 (64-bit), Windows 10 Anniversary Update Pro, x64, and I use the FVD extension with EverSync. I have 8 groups and 1842 dials synced online from Chrome and, when I try to download or merge in the local Speed Dial, it hangs on Apply changes and remains there, almost no CPU work. I let it try for an hour and it just syncs an arbitrary number of dials, sometimes 200, other times 89 and so on. And, if I close the browser and open it back, all the Groups and synced dials are gone. So, what can I do, because I really need this extension on Chrome! -in Firefox it works with no hiccups-
