CloudServices/Sync/File a desktop bug

We always appreciate it when users let us know about problems they’re experiencing with Sync because it means we can improve it! Here are some guidelines on how to file a good Sync bug:

Get the Sync log on the machine you’re having problems

1. In the Firefox address bar, type about:sync-log and press Enter. A list of Sync logs should appear.
2. Find the last log file entry in the list and click on it. It should be called something like error-sync-1307991874508.log.
3. Save it to a file on disk so you can upload to the bug later.
4. If the list in step 2 is empty or only contains outdated logs (you can tell by the dates), go to about:config, find the services.sync.log.appender.file.logOnSuccess preference, set it to true, and sync again. Then repeat these steps (although the filename will now be called something like success-sync-1307991874508.log

File a bug

1. Even if you’ve found an existing bug that may look like the one you’re experiencing, do not add your comments to it. Please always file a new bug, we will dupe it appropriately once we’ve determined the root issue. If you want, you can clone the existing bug or make a cross-reference to it in the summary.
2. Attach the log file(s) you saved earlier to the bug by uploading an attachment. Do not copy & paste the text into the comment field, it won’t hold enough text!

We’re hoping to automate much of this in upcoming versions of Firefox, so that a Sync problem can automatically be reported to us, or at least with just a few clicks. In the meantime, the about-sync addon offers a facility for creating a .zip file with all your Sync logs which might be helpful.
