Hi,

I want to switch from Chrome to Firefox but I have an issue with the Sync feature. It always shows the following error: "Sync encoutered an error while syncing: Unknown error. Sync will automatically retry this action."

I already tried this workaround but it did not work: delete my Sync account, completely reset my Firefox profile, import my Chrome bookmarks (using an HTML file), setup a new Sync account (using the same address email then the previously deleted one). But I still get the error message.

I've seen in other threads that it could be an issue with the history so I also tried to delete it but it did not work either.

Here is my last sync-log file: https://pastebin.mozilla.org/8219943

Thanks for your help.

I've finally found a solution to that Sync issue:

I downloaded the "Places Maintenance" add-on and run the integrity check routine and it seems to have fixed the issue.
