On my 2nd laptop, the extensions are not syncing. I tried re-installing the extensions on the 2nd laptop, but it just says, "An unexpected error occurred during installation." I'd really appreciate your help. The following is the most recent sync error log (I have three more if you need to review them):

It looks like the fault was with the AddonsReconciler process - No data seen in loaded file: addonsreconciler.

With only 2 extensions installed, it might be easier to just install them afresh rather than look for the the cause of that issue.

IMO, the loss of the Legacy extensions and requirement of WebExtensions only set up a "perfect storm" for glitches with add-ons installation via Sync.

Sync doesn't actually "synchronize" the users extensions, it installs them fresh from the Addons server. Gives the user the most up-to-date version of each extension and it reduces the data load on the Sync server.

By the way, Sync error logs are best posted here: And then after posting the error log contents there, post the resultant URL to your submission in this forum.

Pastebin preserves the lime formatting, where this forum software doesn't - it "mungs it up" - making it difficult to follow.

Hi @the-edmeister,

Thanks for the response. I've uploaded the most recent error log here:

I've tried re-installing the extensions, but it fails with a message: "could not be installed because Firefox cannot modify the needed file." I also tried uninstalling/reinstalling the Firefox, but still, have the same issue.

FYI, on my first laptop, I am using 5-6 extensions, not two.

Please help..
