HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.

I believe I got an automatic update to Version 154.0 yesterday on my Windows 11 laptop. When I opened Firefox after the update I got stuck

My Bookmarks appear to still be available, but my passwords are gone. The passwords are still available on my iPhone and iPad

I have tried syncing to no avail.

I need my passwords. How can I get them back?

I am using the same account (my school email), and everything else sync successfully.

Tab groups saved on my Windows PC didn't show up on my Macbook; tab groups saved on my Macbook didn't show up on my Win PC. Is this a feature or bug?

I recently switched to Linux on both my laptop and desktop computers, and I have started having an issue where after closing Firefox, the process does not end fully, leading to a Firefox crash notice after a minute or two.

This seems to only happen when I have sync turned on. It always says "syncing..." and never finishes, and logging out of my account or turning sync off fixes this problem. However, I'd really like to be able to use sync across my two systems.

My laptop is running Pop OS, and my desktop is running CachyOS. Making a new account fixed this error for a few days, and now it is happening again.

Here is my newest crash report: https://crash-stats.mozilla.org/report/index/9adbdc82-3cfa-49b7-8bad-e6e590260319

After reinstalling my computer system, I logged into my Firefox account again, but the data synchronization failed. All my previous data is gone, including bookmarks, passwords, and widgets. What happened? I can't find them in the mobile app either.

Hi there, I have been using the Firefox browser for many years and had saved all my login passwords to various sites on it and I never had a problem with it. But this time, after installing Windows and the Firefox browser, when I logged into my account and turned on the sync, it did not bring any of my previous information. When I go to my account management page, it writes my membership date at the bottom of the page as of today (2026), while as I mentioned, I have had an account on the Firefox browser for many years. How is it possible that my previous information does not exist and it recognizes me as a new user and what is the solution?!

Hello

I've installed Firefox Standard Stable on Windows 11, signed in to my Firefox account, and browsed for about 3–4 days.

I decided to use it on my phone too. After installing it and signing in with the same account on my Android device, about 2,200 browsing history items appeared on the phone.

I don't know why. Before browsing, I always cleared my history on my PC using the following options:

CTRL+SHIFT+DEL and selected Everything, with all 5 options selected.

The browsing history data only appeared on the phone.

My concern is: the data must have been downloaded from somewhere since it was cleared on my PC. So, where are those 2,200 history items stored in the cloud, and how can I delete them?

I don't care about my browsing data. If it were sensitive, I would have deleted my Firefox account by now and used the app without an account.

I love Firefox, and this is a big concern that should be addressed ASAP.

Thank you for looking into this.

In the settings of Firefox there is a search bar you click it to type things in to search settings but I cant search settings? I type "Favorite" and there's no settings for favorites bar behavior? No, I don't want the favorites bar to delete itself after I click on anything. I want my favorites bar to be a favorites bar and stay there and not go away anytime I click on anything. It shouldnt just be there only when I click a new tab.

1) Why does searching the settings for "favorite" not display any favorites bar settings? 2) Why are my Firefox browser settings not persistent between multiple computers when I have enabled "Sync"?

I have linux LMSDE7 Mint, Firefox will not sync. I click on the 3 top right corner lines, sign into Mozzilla, the bookmarks have not synced. Then if I go back to the same lines, it has still the "sign in" field, clicking has no reaction. It seems that mozilla is not signing in I have an other linux version, winux, there I have no problems, it syncs ok.

Hi Moz Support,

I've had this happen several times before, but this time it really annoyed me.

I sent tabs from one Firefox instance to another on another device. I closed these tabs on the source device. These tabs were quite old this time, I'd not opened them in a while - this becomes important later.

On the destination device, let's call it "madbilly's destination Firefox", these tabs didn't arrive. After doing a couple of tests where I sent a tab from my mobile to this instance, I realised that this was a similar problem to what I'd had before, which is one where a Firefox instance/profile for some reasons "resets" itself and it seems to create a new instance in Firefox Sync. Tabs which have previously been sent to "madbilly's destination Firefox" don't arrive, because (I think) it's not registered in Firefox Sync as the same instance. These sent tabs, if closed on the source instance (which I did) are lost, unless one reopens the source instance and Ctrl-Shift+T reopens closed tabs. Unfortunately, in this case because the tabs were old and I hadn't opened them for a while there was no way to do this, because Firefox doesn't remember closed tabs which are not stored in memory (another bug, any fix?), except for looking in old session store backups which I'm going to do after I write this post, though I don't know if that will work.

Also, on Android, because it only remembers 10 closed tabs it's not really feasible to retrieve lost sent tabs this way either, and as there's no access to the session store backups the tabs are definitely lost.

Oddly, when this happens "madbilly's destination Firefox" usually appears twice in the send-tab-to menu, but in this case it didn't. To be able to send to this instance I had to sign out of Firefox sync on this instance and sign in again. Then the same instance appeared twice in the sync menu, the old one being now unreachable.

I'd like to know: 1. Why does this happen? 2. How to avoid it happening? 3. Is there a bug registered about this? 4. When will it be fixed and prevented from happening again.

I generally find that this happens when a Firefox instance isn't shut down properly, which on my old desktop I put down to it running out of resources, but on this shiny new laptop from work that doesn't make sense.

All help much appreciated thanks :)

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.

Cannot get FireFox browser on my Windows 11 computer to sync with my Android mobile phone or the other way around. They both can see each other but they won't sync.

I want to "synch"/ export/migrate my current tabs on my old computer to this computer -- the 'synch now' button in your settings doesnt seem to take it on - please let me know?
