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.

During the last desktop update I lost all of my bookmarks. I’ve tried to sync between my iPhone and desktop but when I finally got paired nothing happened with the sync from my phone to desktop

So I moved from my old Galaxy S21 Ultra into a new Xiaomi 17 ultra.

Installed Firefox and logged in with the qr code thing on my main computer.

Firefox on the phone says it's synced but the list of passwords is empty. Not a single password in the list. Lots of passwords on the main computer.

This worked just fine on the old S21 Ultra.

Any ideas?

This is a completely fresh install on a new phone so not to be ungrateful, the typical good advice about clearing cache and reinstalling is just not relevant here.

Able to sign in to Mozilla account, but cannot find Sync anywhere. Sync is OK on multiple other devices. System also seems unable to load 140.10 esr. Is it possible to sync on esr versions?

i have deleted Firefox and reinstalled it. after logging in with my account i don't seem to have any details with the browser. it is fresh like new. i have tried syncing it but it is still blank as possible

I am trying to sync FF to a new pc laptop from my old pc laptop. I am signed into FF on both devices, but they won't auto sync, even when the (orignal) says that it is. My old laptop is still running on Windows 10. Could this be the reason? If not, please advise how this can be accomplished.

Hey mozilla team,

I have issues with firefox sync as it doesn't sync old search history. Firefox Sync works perfectly for recent search history and chronic, but I imported an old profile (xyz.default) to firefox and logged in with my mozilla account. Started synching so that the old profile's history gets merged with the current one. It doesn't. I can see it in the imported old profile, but if I check history on another device, it's not there (aka only locally but not synced yet).

Is it generally possible to add an existing profile and then syncing it to merge it with the current search history one?

Three times now this year, I have been automatically signed out of my Firefox account on desktop with no cause. No updates or data clearing to cause it. Every time when I log back in despite having my Firefox synced to my mobile app, my bookmarks & passwords all break. Passwords deleted, bookmarks dysfunctional. I try syncing to restore them. Doesn't work. If I restore from backup, it fixes my bookmarks, but not my passwords.

After the second event like this, I changed my Mozilla password, but seeing as this just occurred a third time this year, that didn't stop it. I reiterate: I DID NOT SIGN MYSELF OUT. I DIDN'T DO DEVICE MAINTENANCE THAT WOULD HAVE SIGNED ME OUT. Sync SHOULD restore these but isn't.

My personal laptop was being repaired, and I was using my mom's old laptop until mine was fixed. I logged out of her Mozilla account on that laptop and signed into my own. Now that I have my personal laptop back, all of my passwords, bookmarks, and extensions are mixed in with all of hers. I don't know what to do, and I'm worried that if I remove bookmarks from my account, it'll create a domino effect that results in a catastrophic Mother's Day.... Please help, I'm not good with technology, I'm just a geology major.

I have a Firefox account. I am logged into my Firefox account on both my desktop and mobile phone. I want to sync them. I cannot do it. I press the three horizontal bars and it does not work.

你们家firefox beta安卓端删除数据重新登录后点立即同步有效果 一退出重进 或者连个vpn或者连个vpn然后断开vpn 就出现以下问题 1.按了之后一直显示 同步中 2.按了没反应 问题是持续的 也就是说一旦立即同步用不了了就得删除firefox beta的数据重新登录 太恶心人了

希望尽快解决

感谢你们

I have been trying to clear out my bookmarks fro several days now and every single time they are restored. I have tried unsyncing my phone and computer and saving backups to try to force restore it to the cleaned up version but it always restores every single bookmark even to the original folder after I moved them around.
