Preliminary Checks

• I have read and understood the important section above.
• I have searched existing issues and avoided creating duplicates.
• I am not filing an enhancement request.

• I have checked that this issue can be reproduced once I removed all my Mods and Custom CSS.

What happened?

Since the last update, bookmarks no longer synchronize.
However, they synchronize fine on Firefox.

Expected behavior

Bookmarks sync with a Firefox account.

Actual behavior

Bookmarks no longer synchronize with a Firefox account.

I've since redone my sync and it works the first time from firefox to zen, but after I've done changes in zen the sync fails.

I can confirm this issue as well on 1.18.5b (Firefox 147.0.3 Arch Linux AUR install.

Environment:
Distro: EndeavourOS
Desktop: GNOME v: 49.3
Kernel: 6.18.7-zen1-1-zen

The following web browsers continue to sync my bookmarks from Mozilla:

Android

• Iron Fox

Arch Linux Native installs:

• Firefox 147.03
• Floorp 12.10.2-1

Troubleshoot:

-I did delete all my data, re-installed Zen Browser from the AUR. Then setup Firefox Sync again. All bookmarks are synced from that time. But if I bookmark anything new in Zen, it is not synced to Mozilla.

Hi, @Vinetzou. I'm Dosu, and I'm helping the desktop team manage their backlog and am marking this issue as stale.

Issue Summary:

• You reported that after updating to version 1.18.1b on macOS aarch64, bookmarks no longer sync with your Firefox account, although Firefox itself syncs fine.
• A sync log shared by ChrisS85 shows a UNIQUE constraint failure error related to bookmarks during sync, causing partial sync failure after initial success.
• Another user, rsramkis, confirmed the issue on version 1.18.5b with Arch Linux, noting that new bookmarks added in Zen Browser do not sync back to Mozilla.
• The problem appears to be a persistent sync error affecting bookmark updates in Zen Browser across multiple platforms.
• The issue remains unresolved with no current fix or workaround provided.

What's Next:

• Please let us know if this issue is still relevant with the latest version of the desktop repository by commenting here to keep the discussion open.
• Otherwise, this issue will be automatically closed in 10 days.

Thank you for your understanding and contribution!

Hi. I have re-tested between Firefox 150.0.2 and Zen Browser 1.19.12b on Arch linux and can confirm that bookmark syncing is working. When this got fixed several releases ago I noticed the bookmark differences did mess up my booksmarks. So I deleted the sync off the problem computer and manually re-syned. Issue can be closed from my perspective. Thank you.
