Firefox 技術支援討論區

I've read all the suggestions but can't get Firefox Sync to transfer the open tabs from my old PC to my new one. I'm signed in on both to the same account, both are on my LAN with a wired ethernet connection, and I've checked every box in the "what to sync" field. When I click "Sync Now" the icon spins for a few seconds like it's doing something but the tabs from the old machine do not appear on the new one as I expected them to. Nor can I get them by closing and doing a Restore Session.

This seems pretty straightforward and how most users would expect it to work - am I missing something? If not, why isn't it working?

Synced Tabs from other device did show till yesterday but no longer showing

It just says "connect another device"

My other device had to be 'factory reset' but that was some time ago (nearly a month) and the tabs from it were still showing till yesterday in my main device, Now they've disappeared, is there a way to get those tabs back??

I read somewhere that those tabs are maybe on the Firefox server, is there a way to access those???

I tried to login to firefox sync on a different system due to repair. My entire data is gone and all passwords are also gone. What to do.

I even tried login with username and password apart from google sync. It still didn't worked.

Hi team, have reviewed few thread on Sync issue, but none was explicitly touching the issue I have. Running latest version on different PCs ( both Win10), using same account, I can't "send to" tabs among them. They are simply not in mutual device list. No problem to see mobile (Android here) devices in same account.

So, is this a recognized issue on PC with same account? I may just guest about HTTP "user-agent", same "display name" in Sync account and similar stuff in possible conflict, but better leave this on IT pros.

General issue is with speed of sync. If I open a tab, sync the device, then send to other device, sync that other too... and it's not instant there, even not after minutes. What could this be?

Though two questions, I thank for every reactions to them. BR Peter

I cannot log into my Bank or puzzle> No internet? Trouble started with Firefox upgrade to must have Edge? Can you call me [removed phone# from public forum]. I am a senior and technically challenged and must make these corrections. Why did you upgrade and change everything?

Hello,

I synchronized my FF with another computer and made the mistake to remove all passwords before logging off sync so I lost all my passwords but a few.

However I still have the logins-backup.json on my main computer with everything inside. However when I replace the 'logins.json' by the content of logins-backup.json it's always reverted.

How can I replace all my passwords with the logins-backup.json content ?

My windows got corrupted had to reinstall everything and this means i have lost my old Firefox account password is there anyway i can get all those saved passwords as i need them. Any help would be great

I'm self hosting a firefox sync server on unraid. If I set it up on the local network, it works. I use this public address in the docker container http://localhost:5000 and the about:config server as identity.sync.tokenserver.uri = http://localhost:5000/token/1.0/sync/1.5.

Now if I switch to my reverse proxy, I use this public address in the docker container http://firefox.mydomain.com and the about:config server as identity.sync.tokenserver.uri = http://firefox.mydomain.com:5000/token/1.0/sync/1.5. It does not sync. I get an error if I use that url in the browser link. If I make it http://firefox.mydomain.com/token/1.0/sync/1.5 (taking out the port number), my browser displays a json page. But if I remove the port number in the about:config and make it identity.sync.tokenserver.uri = http://firefox.mydomain.com/token/1.0/sync/1.5, it logs me out of the firefox account.

The reverse proxy is passing port 5000 through, so that is why not specifying it returns a valid browser page. The about:config seems to need the port specified to work. Otherwise I'm getting logged off. Is there a workaround to this?

my computer broke about 2 months back and i am wondering if i can access the tabs from that device from another device since the original was synced (or i.e. is the a function in Firefox that lets me see all synced tabs from all connected devices)

going to the regular synced tab area there isn't anything from that computer there,

Firefox v.99.0

Hello Everyone,

I am not sure what has happened but I had tons of passwords saved in my Mozilla browser. I have been using this since 2019 or 2020 and saved all of my passwords there. What happened is I was using my laptop and wasn't aware that the charger is not plugged in. While working my device turned off because of no battery. I connected the charger and restarted my device like normal. After I opened my browser(Mozilla Firefox) and ctrl+shift+t to open all the recently closed tabs, I was amazed to see that it restored many old sites like 1.5 month old websites instead of the one's which I was using. However, the recently closed one's were showing in the history. I opened the tabs from history that I needed and started using it normal. I have using Mozilla Firefox for good 2 years I never felt the need to remember any of my passwords. Everytime I have to create an account on any of the sites I just create a password once, at the time of sign up only and then click on SAVE PASSWORD so I don't have to remember it. I am guessing this is the normal practice that everyone does or may be a cast majority. I was doing my routine work, I tried to login to my account using the same way like you put in your email in the email section and then click on password section and select the user/email you want to use a password for and sign in. BUT TODAY WHEN I FOLLOWED THE SAME PROCEDURE, IT DOESN'T SHOW ME ANY SAVED PASSWORD WHICH WAS QUITE SURPRISING TO ME. I OPENED THE PASSWORD MENU FROM THE TOP RIGHT AND I WAS SHOCKED TO SEE THAT THERE WE ZERO, LITERALLY ZERO SAVED PASSWORDS. I REALLY NEED HELP WITH THIS BECAUSE THOSE WERE SO MANY PASSWORDS LIKE SERIOUSLY SO MANY.

THANK YOU, AMIR

Is there a maximum number of tabs that can be synced? I have about 800 tabs on my old computer, but when I look at the synced tabs in the sidebar on the new computer, only about half of them are listed. The oldest 400 or so are missing.

And yes, I realize 800 tabs is insane. But that's another discussion. :)

Hi, when I had cleaned out all my bookmarjks duplicates (and they were many 50.000 accumulated through the years)on my Linuxmachine and turned on my Windows 10 machine they were all back. So my question is: what data is saved when syncing with Firefox sync? And I dont mean the different types you can choose between ,no I mean: when I change one thing on onea logged in firefox on one machine doesnt that change the status of, and in my example the bookmarks on the other machines? Or is it the other way around, namely: will the second machine with all the duplicate bookmarks change the sync-"base" so they will be back on all other machines again? Very confusing especially if youre logged into moire machine then one at the same time. Please answer me, I really need to clean up my firefox's accumulated duplicates pretty quick. Sincerely Wal

Long time ago I had this email let's say x@yahoo.com after some years i delete and made a new one x@gmail.com. On my PC every time I try to log in it goes like this: I put my x@gmail.com i put my password and it sends me a code on the same Gmail address... Very simple right? I put my verification code in and it says wrong password for email x@YAHOO.com... WHY DOES IT CHANGE MY EMAIL FROM GMAIL TO YAHOO ? I'M LOSING MY MIND I CAN'T LOG IN ON FRESH WINDOWS INSTALL!!!! I even reinstalled Mozilla, I've cleaned everything there is too be cleaned from the browser and same stupid "feature". Whyyyyyyyy????

In security I have use primary password enabled. I have sync enabled. When I first open Firefox, the "Please Enter your Primary Password" dialog appears twice. At first I thought I was repeatedly miskeying the first time. But then I noticed that if I drag the modal dialog box, then a second box pops up behind the first. In fact, some times, I can start typing when that second dialog appears. As in the case today when I just caught it. Please see screen shot attached.

FireFox 99.0 Windows Enterprise 10 OS Build: 18363.2212 I am on a Private Browsing window when I see this error.

Please do what it takes to cause me to not have to enter the master password twice.

Thank you,

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

I have reset my Windows 10 OS with the windows repair tool, I have since lost all the data linked to my account such as password, bookmark, profile settings, etc...

I tried to sync multiple time to no avail.

Firstly; I am 77 years and represent a non understanding in computing. I recently changed fierfox code to ensure contact between my mobilephone and a table computer. I dont remember the old firefox code. My bankid does not work after change. My question; do I need to give new codes to bouth devices shall i also change other codes making Sync. Thanks for help and sorry for my halting english. Yours kjell ryden
