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?

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'm still using the old browser because the new browser, the one before that popped up today, doesn't work well on my old desktop computer. New one today requested to move passwords from cvs file and bookmarks from an html file. When I tried to search for these things my computer couldn't find them. But when I went back to the old browser, all bookmarks passwords are there.

Why is Firefox asking me to perform these functions anyway? There is no explanation as to what this is. Is programming at Mozilla really gone downhill so quickly that they forgot how to make their service user friendly?

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.

I cannot log into my account and synchronize my data, logins and passwords. I downloaded the latest version of the browser on the official website. Below I will send screenshots proving that there are no buttons or anything that would indicate at least the slightest login to your account. BUT YOU'RE SHOVING YOUR ****** AI BOT EVERYWHERE.

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 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.

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 my computer and phone and it sends a code to my email address. but out of the 3 times I have tried I have received 2 codes but at least 20 minutes after sending so I cannot use them. I am using Thunderbird for my email

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.

I have two computers that I use and I have them setup the same. Both have Windows 11, both are the same model, HP. One computer has 260 passwords and the other has 253 passwords. Why aren't they the same. Same sign in name Ronald Cogan, same email, same password. But when I bring up the one computer it shows 260 passwords and when I move over to the other computer it show 260

Dear All, I recently reinstalled Windows and updated to the latest Firefox. When I tried to sign in to sync/restore my bookmarks, Firefox could not recognize my password. I reset it and used the new password, but the bookmarks that appeared were outdated, and not all information synced to my current account.Could you please advise on the steps (or a quick solution) to fix this?Many thanks for your support in advance.Kind regards, Tareq Zeyad

I have many computers that I put Firefox on, and had no problem getting my bookmarks on them as long as I sign in to my account. However, I just had my desktop redone (that previously had Firefox) and now, after I have downloaded Firefox, I cant get my bookmarks when I attempt to do the syncing. Please help
