It seems to be working for me in chrome and firefox.  In IE it still is not working (get "something wrong happened, send info to developers?" popup, not a crash, but the bookmarks don't sync).  

I'm using Windows 7 Enterprise, IE 11.  

I continue to get a popup error every time I try to synch.  More importantly, the bookmarks aren't synchronizing.

I installed the new version this morning (1.2.0.0)  I get a whole lotta popup alerts about "An error occurred, do you want to send information to the developer?"  (like, 5-6 times this came up at various stages of the process).  But it does seem to have recovered and done an actual synchronization.  Not ideal, but better than not having any sync at all.

I have the same problem, but my machine is Windows 7 Enterprise (IE11).

Firefox and Chrome (and chromium-based GhostBrowser) seem to work.  It's only IE that crashes.
