Actual behavior

Something messed up in MAC with Sync, and it's syncing back the erroneous data to my browser.

Expected behavior

The ability to wipe the data synced and start from scratch.

Steps to reproduce

1. Create some containers
2. Something I'm not aware of breaks
3. Get an ever-growing list of duplicate containers populating and slowing down Firefox to a crawl.

Hi there.

To erase Sync data, try this (turn Sync off first in the extensions preferences):

1. Open extension console: Go to about:debugging#/runtime/this-firefox, select "Inspect" on Multi-account Containers, and select the console tab
2. Type browser.storage.sync.clear();
3. Manually sync through the browser (hamburger menu, your account, Sync Now)
4. repeat step 2 and 3.
5. To make sure it's working, you can type await browser.storage.sync.get();. It should return and empty object if it's working.

However, I ran into a problem during development where I could not even clear sync and basically had to delete the account and create a new one under the same email, so I hope that hasn't happened to you. That appeared to be a bug with Firefox Sync itself and not anything to do with Containers.

Your bug looks like an issue with containers creating a feedback loop. I think we saw one other case of this, so it would be interesting to reproduce it.

[drod3763]

If I follow those steps and I do not get an empty object, what does that mean? Should I be doing something?

@kendallcorner oh, interesting, did this get filed upstream with the sync team anywhere?

[foss-]

Sync team is aware. For me above steps resolved the problem. Thanks for posting and hope you can understand why this is happening in the first place and prevent it. Thanks for working on the container extension.

[runiq]

I'm having the same/a related problem. There's a 10MB error-sync-<bla>.txt file created every few minutes, which regularly fills up my harddrive. I tried the steps in https://github.com/mozilla/multi-account-containers/issues/1661#issuecomment-591506621, I got the empty object, but Sync still generates the file.

Should I file a separate issue?

[rfk]

There's a 10MB error-sync-.txt file created every few minutes, which regularly fills up my harddrive. [...] Should I file a separate issue?

This could be an unrelated sync issue, but it sounds worth investigating. Could you please file a separate bugzilla bug so the sync team can investigate? Direct link to bug form:

• https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=Sync

If you're willing to share them, please attach a sample of one of the error logs for investigation.

Done, thanks!

[jonhoo]

Is it possible to reset just the sync data for multi-account containers?

[Hard-Wired]

Resetting server side data would be incredibly helpful!!!

[fantom-exe]

Any status updates on this issue? I still experience this issue every week. I reset sync using @kendallcorner method and it seems to make a difference for a while until one of my devices (I have 3 devices syncing to my account) starts syncing and the issue pops up again. Then I repeat the process to buy me another week.
