I'm the I.T. Director for a school and we use the Securly filtering system. I can't get Firefox sync to work behind this filter. What is the URL that Firefox is trying to connect to for sync so I can add it to the whitelist? Or, IP address. Also, does Sync use my system DNS or does it have some sort of internal DNS that it queries for sync? Because I recently found out the hard way that I have to use the Securly's DNS IP's or nothing works.....

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 tried to sync my desktop and mobile today. Nothing loaded to my mobile a fact I am now gratefull for because my desktop did sync with the cloud ERASING an entire year of deleating broken bookmarks. What I want to know is how to deleate the cloud so this never happens again!

For years, I've been using FF on desktop (Linux), tablet (Android) and phone (Android - Samsung S24+). Sync has never been a problem until two weeks ago when FF on the phone has either refused to sync when I tapped the command, or hasn't synced for many hours or sometimes days (which is why I tried to do it manually). So, I signed out of my FF account on all 3 devices and then signed back in. The desktop computer and tablet are syncing normally, but the phone still won't sync. When I tap the 3-dot menu on the phone and then my name, it says the phone has NEVER been synced and tapping the sync command does nothing. Under "Choose what to sync", all options are checked, but greyed out. Can't change them, in other words. When I access bookmarks on the phone, it properly shows what was there before the last sync. The phone is running FF version 150.0 Build 2016155439

Help!

Need help please to fix this problem: Firefox does not open QR codes on my iPhone. On my phone, the toggle for Scan QR codes is turned on. I open the camera on my phone, point it to a QR code on my laptop screen, Firefox on my phone opens in a new screen -- but nothing happens. What is missing? Thanks for helping me.

I don’t understand what’s going on, but this is not working for me and I am not an eight by person who can get or understand how to use this software I’m a senior and this is frustrating that’s all I can say

Hi! I try to synchronize my mobil iphone 14 and mac airbook wit firefox. I tried new installation firefox, restart iphone, scanning code or choose option e-mail- i always ends on white, empty screen. If i go back than i get the info - could be that there is no internet. I tried wlan and whitout wlan. What else can i do to synchronize?

I opened up Firefox for the first time in a while on this newer laptop, and all of my bookmarks are missing. I recently opened Firefox on my work desktop, and they were all there.

Any help would be appreciated!

it can be useful if u create a system of syncing which actually works, why my passwords dont sync when i log in and also i had to put my exact same passwords 6 times before the stupid system recognized it was correct, the fuck is happening i had changed devices before and this never happened i dont know why now but im very upset

My internet connection is with Comcast, whom has told their customers that they will no longer be allowing email addresses with their company’s name. To this end I have been trying to move my old email accounts over from them, and I'm facing a lot of problems. However, since I was able to change the email in the Mozilla account today, I may be able to do it now. Also, please update my computer info to windows 11. Educated guesses below are correct.

Thank you V

I have finished my setup. But it keeps saying "finish setup" in the upper right corner of the browser. I have completed all the steps. I want to sync this desktop to my mozilla account. What do I do?

please tell me how to solve the problem in the one sentence i was asked to provide. i have tried syncing from both devices and have disconnected and reconnected to se if that helps, nope. i have no problem syncing bookmarks from desktop to android but the other way around is not working

I was using Firerox Beta on Android and yesterday or for the last couple days my Firerox account would keep getting logged out as in I'd have to sign in again and again to sync or send tabs to other devices. (It would repeatedly say sign in again to sync even after I sign in repeatedly).

I uninstalled Firefox Beta and installed Firefox stable on Android. No such issue so far.
