I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

I know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

For the past two months, I've been trying to sync Firefox (114.1.1) on my Samsung Galaxy phone (SM-N950U) with Firefox browser (114.0.1) on my Windows 11 Home laptop. On the phone, it works fine. On the browser, when I go to firefox.com/pair ... I get to the screen with the bar code, when I scan that bar code on my phone, the windows Firefox browser gives me an Error 500 (see attached.) Your help is appreciated!

Hi Support,

I have always been struggling with the idea of syncing two devices, that is main and secondary devices, and that when logged out of the secondary device, user details such as passwords, booksmarks and other important things are left bare on that browser or secondary device.

It is my believe that, after completing whatever task that led users to sync both devices, the moment the user logs out on the secondary computer, or any of the computers, the passwords, bookmarks, history and other essential details should not display again on such computer or browser anymore but apparently thats not the case with Mozilla Firefox browser.

Kindly look into that and work on it....THE SECURITY AND SAFETY OF THE USER IS LEFT WIDE OPEN!!!

Following direction on Help Page - Trying to sync tabs, bookmarks etc from one laptop to another. In settings, devices are said to be logged in and sync set to sync pretty much everything. Clicking the menu top right - only shows my email @ the top, then New Tab etc - but nothing about "Sync Now" or "Sign In" What am I missing? TIA, Jean

Both my computer and my tablet are logged into my Firefox account, the page at accounts.firefox.com lists both devices, yet for some reason they won't sync. I've synced two mobile devices before, and it worked fine. I've spent a good portion of today trying to figure it out, and have gone half mad from frustration. Please can you help me? Thank you!

I work at a small company I had to do a windows recover on a users laptop. He logged back in to firefox which had all of his passwords saved and now none of them are populating is there anyway to get them back? They are vital to his job.

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.

I do not know what I'm doing wrong but my main pc won't sync it's tabs to my other devices. It just says "no open tabs".

I'm able to see all the tabs open on my other devices but not my main pc's

I changed my firefox account password and lost all of my saved logins and bookmarks is there any way to restore it please help its very imp coz i dont have backup.

Lately, Bookmarks has been deselecting itself in Sync on all three of my computers. This has happened twice in the past few days. No problem with other Sync items.

Factory reset android phone, trying to sync with my account. Tells me my password is wrong, but it's the SAME as what's stored in the cookie! If I try to change it, it tells me whatever I've entered as a new password is wrong? Can't win!

I have had problems with sync before, giving me bookmarks I didn't want, etc. But I want to try it again.

I have a Firefox account to log into with sync, but I would like to delete all the data (bookmarks & passwords), and then sync all my firefox browsers to one profile that I have set up on FDE on my laptop.

So I'm thinking I need to first delete all my current data on Firefox Sync, and then log in only with my FDE profile, sync that, and then log in via other browsers and sync those. But how do I make sure that no data gets placed onto my FDE profile from other browsers via sync?

On my main laptop I built a nice homepage with shortcuts that I use regularly. I would like this exact homepage on all the devices where I sign in with my Firefox account. Instead, every time I sign into a new device and sync, my homepage is completely destroyed and scrambled on all devices, including my main laptop and I have to painstakingly recreate the homepage I want. What is going wrong here? How can I set up one homepage on one device that will be synced to all other devices?

My company just pushed out new group policies for Firefox that blocks use of Firefox Sync. That also, apparently, blocked use of my saved logins and passwords.

I can find the encrypted password files in my profile: key4.db logins.json

but I can't open them.

Is there any way to get my login and password information?

I recently moved from Opera to Firefox, and moved all of my passwords by making a CSV file then importing them to Firefox, but they’re not syncing? While on my PC it shows all of the passwords, my phone only shows my password for my Firefox account, the only password I made rather than importing. Any help will be very much appreciated.

My computer died today due to water damage, which means I can't turn it back on again. I got a new computer, I've looked all over the Firefox support websites, and can't find a solution as to how to get all of my Firefox data onto this new computer. I tried the profile page, but it looks like a profile for my old computer's Firefox never even existed. I have no idea where to find any of my old data.
