Hi

Thank you for your question and thank you also for using Firefox Nightly. By using Nightly, you not only are seeing new features before they are released, but are also helping make the next versions of Firefox better through your feedback and bug reporting. Thank you!

Please appreciate that by using such a pre-release version of Firefox, you may encounter some unresolved issues. I recommend that you file these at Bugzilla so that they can be tracked and fixed.

If you have a copy of your desktop Firefox profile from your old PC Firefox, you may be able to recover your bookmarks and other data. This article will help you look for the files on the old profile that you can then copy across into the new profile folder.

I hope this helps, but if not, please come back here and we can look into a different solution for you.

You can check the about:sync-log page via the location/address bar to see if there are recent error logs available.

You can upload a recent log if the log is too big to put in a reply.
