Diễn đàn hỗ trợ Firefox

All my saved passwords are missing. I am synced and logged into an Android phone. I usually use an iphone but have not checked syncing there yet, or on a computer/laptop.

It would be nice if the sync function actually synced something other than just my bookmarks and my browsing history between my Firefox installations. I mean, I checked all the boxes, so theoretically it should...but no...it never does. Toolbars don't sync -- I know, for some reason that's "by design" (or laziness?) -- Settings don't really sync much (maybe a few do when the moons of Jupiter and Uranus are in perfect alignment).

Could you maybe consider syncing the various exception lists in the Settings?

Hello there! I have Firefox on both my (Windows) laptop and (IOS) mobile device. Several months ago (January or February, maybe?) I had to delete Firefox from my laptop and reinstall it to fix an issue. No big deal. However, whenever I check my synced tabs on my mobile device, it still shows the tabs from before I uninstalled it on my laptop as well as the taps currently opened on my laptop. It appears as if they're two separate devices. I already checked the "Connected Services" section of my account settings, and my laptop does not appear twice. I was hoping someone could point me in the right direction of how to remove the previous version of Firefox from appearing on sync on my mobile device. TIA for any help!

I have used Firefox bookmarks via sync for 20 years!! My previous computer is bricked and cannot be accessed. I have a fancy sync code but when I download Firefox on my phone or new computer, it’s like I’m a first time user. It offers me a new sync code but won’t allow me to use what I have. Are my files recoverable? Can I wipe from my old machine too?

Hello, I am transferring to a new device but my device is not syncing and just loading even when I tried to close and open Firefox. I've tried to also log this in via support but to no avail. Appreciate any help on this. Thank you!

I have profiles on desktop , i had enabled sync in all profiles when the feature was first introduced. the account icon always showed that it is syncing , but in the sync tab , no visited tab list appears of any profile in both the desktop .,, i installed firefox on the android today to check synchronization but its tabs never show in desktop profile and the android tells last synchronization never....neither the desktop tabs appear in android history

Dear Mozilla Team, I installed my Fieefox on Linux Mont on an old Laptop I use as my daily machine. Firefox however after login does not sync to my previous installs. I have installed and removed firefox on my mobile (iphone), with no change. Also re-installing and singning out, signing back in did not help. What can I do to get all my bookmarks and PWs back?

Out of 3 devices, one is not syncing at all. Here are my logs:

It says Login failed, but I have successfully logged out and back into my firefox account.

I am often adding bookmarks on one device and needing it on another one. Synchronization is set up properly on my devices and does some of the job, but has a bug:

- I add a bookmark on my iPhone. - This bookmark is synchronized to my Macbook, see picture Bild1 - When opening this bookmark, the URL is not shown in the adress bar as a bookmarked website, see picture Bild2 - But what makes it more tedious and contrary to the idea of the tool: when entering key words existing in the bookmark's name, the bookmark is not shown in Firefox's suggestions, see picture Bild3

Since Mozilla no longer supports Lockwise, I am trying to sync my iPhone to my laptop to get all my passwords. INstructions tell me "Sync Firefox on your phone or tablet 1. Open Firefox on your mobile device. 2. Go to the menu ( on iOS or on Android) and tap Sync and save data 3. Tap Ready to Scan and hold your phone over this code" First of all, this choice does not exist in the iPhone Firefox menu. If I go into "Settings" and press "Sync now" none of my passwords show up within Firefox. Please help. Thank you.

Now i am affraid to use firefox browser on my pc as i'm scared of deleting all my bookmarks. Please help me, thank you

Hello Mozilla. I am logged on to my Firefox account on a new computer. Although I have logged in, I haven't experienced Firefox automatically syncing my bookmarks and extensions as I did two computers ago to this last computer. I have tried syncing numerous time (pressing the sync button in my account) to no avail. What do I need to do to get this working? Thank you for your time and attention.

I can't get open tabs to sync from my other computer. Bookmarks synced and other info but I don't see anything about tabs from other devices. I've synced both ends, both are logged in and I've selected open tabs in both. Nothing,
