Synchronization Failed. Error is Firefox service initialization failed.

Question

Synchronization Failed. Error is Firefox service initialization failed.
Synchronization Failed. Error is Firefox service initialization failed.<br />
I have been having this issue for quite some time with Firefox. I am using the Nightly build (23.0a1) and have been using for more than 2 years. Synchronization was working fine till a few weeks ago. Synchronization of XMarks on Chrome Dev works fine and no problem. It's only with Firefox. Things I've tried but no success:
1) I deleted my profile off of xmarks and created a new one and tried syncing again. No success.<br />
2) deleted firefox, deleted the profile folder under AppData. Reinstalled everything fresh, and still no success.<br />
My log file shows the following... Not sure what to check. Anyone help me? Thanks!

Answer 1

Re Patrick's suggestion above, I was able to get Xmarks working again on both my Win 7 laptop and desktop today by uninstalling my Aurora browser completely and then installing the regular release version of Firefox, 20.0.1.
When I uninstalled Aurora, it asked me if I wanted to keep my customizations and personal data, and even though it meant a bit more restoration work later, I decided to try erasing all my Aurora settings and data and starting fresh. (But before doing so, I backed up all my bookmarks by exporting to an html file and my add-on settings via Firefox Sync.
After that, I installed and started with a clean slate version of regular Firefox, and proceeded to then reinstall my various add-ons and import my saved bookmarks from the html file. As soon as I re-installed Xmarks and re-logged into my Xmarks account, the automatic syncing process went fine and no more error messages or failures.
I had been using Aurora for months prior with Xmarks and never had any syncing problem until the first week of April. And at that point, the syncing function broke on both my laptop and desktop, which were both running the daily updated versions of Aurora. So I'm believing that something was changed in Aurora that caused this problem.
