Hi! Today I synced a tab from my Android device to a desktop PC. The link arrived successfully, but on the Android device many many inactive tabs disappeared without a trace(searched history, recently closed etc.). looking up about:sync-log I only got txt files of errors, no trace of links. Can you help me get back my closed tabs? TY

I changed the password of my Firefox account recently, which logged me out of my Firefox iOS app. When I'm prompted to scan the QR code to re-establish the pairing, nothing happens. When I choose to use email instead, I get "unexpected error". This happens every time I try to re-pair. Please help me sign in to Firefox iOS.

Hi everyone,

I’ve been experiencing synchronization issues with Firefox lately.

Current situation: Tabs sync correctly between devices, but bookmarks and passwords no longer sync between my iPhone and my computer.

I’ve also considered an issue with profiles, I currently have three Firefox profiles:

• default-release (currently in use)
• default
• default-release-1

I also used Firefox Troubleshoot Mode (restart with add-ons disabled) to test the issue.

sync-log : The sync-logs show many success-sync entries and only a couple of error-syncs. There are no obvious connection issues (I’m using a shared connection in a rural area). However, bookmarks and passwords are still not syncing properly across devices.

Observed behavior: Sync is active and "functional" Only specific data types (bookmarks and passwords) are affected The issue persists even after signing out and back into Sync, and restarting Firefox on both devices

Checks already done: Sync is enabled for bookmarks and passwords Sync logs mostly show successful operations rather than errors

Hypothesis: A Firefox profile conflict

Question: How can I restore Sync properly without losing my bookmarks, passwords, or other data?

Thank you for your help.

Hi all, Starting at the weekend or end of last week I think, when I send tabs to another device when that device is switched off then when I open Firefox on the other device, the sent tabs are loaded in private browsing windows, not the main window with my saved tabs in. Sometimes all sent tabs arrive in one private browsing window, sometimes in one private browsing window for each tab. As I can't drag private tabs into the main window this is really annoying! How can I stop this happening please? Cheers :)

Anybody else having issues with this feature? It had been working well to send tabs from my tablet and phone to my desktop computer, which I have been doing due to the lame way that FF uses for filing bookmarks into folders on the mobile devices.

A few days ago I started seeing "unable to send" popping up after a delay, instead of "tab sent" which typically appears immediately. Sometimes, the tab is sent even though it says it wasn't and sometimes it will send it after repeated attempts, and other times it doesn't. My wireless network and ISP connection are high speed and reliable.

So far, the problem only appears when trying to send from mobile to desktop. Sending from the desktop to mobile seems to work fine. The problem started while using 147.0.4 and persists after upgrading to 148.

Hello Mozilla Support Team,

I am writing to request assistance with recovering my Firefox Sync data.

I recently reset my PC and after reinstalling Firefox and logging back into my Firefox account, my bookmarks and saved passwords are completely gone. I believe the sync may have overwritten the server-side data with an empty local profile after the reset.

Account email: [edited from public] @gmail.com Approximate date of data loss: 02 25 2026

I had been accumulating this data for approximately 1 years and it is very important to me. Could you please check if there is any backup of my sync data on your servers that could be restored?

Thank you for your help.
