## Environment - **iOS Device**: iPhone with Firefox for iOS (latest version) - **PC**: Windows 11, Firefox 133.0 (latest stable) - **Account**: Same Mozilla account on both devices (verified) - **Sync Settings**: All sync options enabled on both devices, including "Open Tabs" ## Problem Description I'm experiencing an issue where "Open Tabs" sync is not working between my iOS Firefox and Windows PC Firefox, despite all other sync features working correctly. **What works:** - History syncs perfectly between iOS and Windows - Bookmarks sync correctly - Account is properly connected (confirmed via QR code pairing) - "Device connected" confirmation was shown after pairing **What doesn't work:** - When I go to `about:firefoxview#syncedtabs` ("Tabs from other devices") on Windows PC, it shows "どこからでもタブを取り出す" (Get tabs from anywhere) with no devices listed - The iOS device does not appear in the synced tabs list - Even though the same tabs appear in History (proving sync connection works), they don't appear in "Tabs from other devices" ## Steps Already Taken 1. Verified same Mozilla account on both devices 2. Verified "Open Tabs" sync is enabled on both iOS and Windows 3. Performed QR code pairing - received "Device connected" confirmation 4. Manually triggered sync on both devices 5. Checked History - it syncs correctly (tabs I opened on iOS appear in PC's history) 6. Waited several hours for sync to complete 7. Restarted Firefox on both devices ## Expected Behavior Tabs open on iOS Firefox should appear in Windows Firefox under "Tabs from other devices" (about:firefoxview#syncedtabs). ## Actual Behavior - History shows the tabs (proving sync works) - "Tabs from other devices" shows no devices and no tabs - iOS device is not recognized as a synced device for tab sharing ## Question Is this a known issue with Firefox for iOS and Open Tabs sync? Is there a way to fix this, or is this feature not fully supported on iOS? Thank you for your help.
