Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

I have two desktop computers and both Firefox accounts are in my name. I have had this site up for years. Now when I click on one specific web site it won't come up unless I got to Firefox's web browser and click on the three bars, and under my name click on sync now. Then the site comes up. The problem is I have to do this each time, on each computer. I have tried all kinds of troubleshooting to no avail. Help.

I have 3 desktops and 2 laptops with Firefox sync turned on. Occasionally the bookmarks on all devices are synced with an older version of bookmarks. I'm guessing it's from one of the laptops that hasn't been turned on in a few weeks and now is on. Is there not a way to prevent an old set of bookmarks from replacing a known 'good' set of bookmarks? Thankfully I have my bookmarks backup turned on and can restore them but would like to know if there is a solution to keeping bookmarks current and stable on all devices, even those devices that aren't regularly used.

I still use the Quantum 96 portable along with Firefox ESR 52.9 for certain sites due to the superior customization and functionality of the latter via extensions that do not work on Quantum. However, I would like to sync the ESR passwords with Quantum, but I cannot login into Sync on ESR since "sign in" results in "Blocked by Content Security Policy."

I have stored some password with my account. Recently from past couple of days all passwords got cleared and not no passwords are shown. Could you please let me know what needs to be done.

I installed Firefox on a new device and initiated a sync for multi-account containers - it promptly synced in the wrong direction. It eliminated all customization from what should have been the source (the existing device), overwriting it with the default settings of a first-time installation. I was quite surprised.

This leads me to a couple of questions.

1. Is there a sync version history or any way of rolling back a sync? 2. Is there a way to explicitly choose the sync direction?

Quite honestly it is very confusing that there is no reference whatsoever to which way an initial sync will go. I was hesitant to risk this, decided to trust it knew what to do (even though it didn't give me any indication that it did) and lost my gamble.

Firefox knows the device names, so can I suggest some basic reassuring UX be inserted into this process with something like "Initiate sync from X-DEVICE-FIREFOX to Y-DEVICE-FIREFOX?". A bit of clarity would be helpful here, as well as a way to roll back a syncing mistake instead of just having to gamble possibly losing hard-won customization with no going back.

Or have I completely stumbled past some obvious place where everything I'm requesting exists and is accessible already?

Thanks for any help anyone can provide.

I want to sync my desktop and mobile login lists. I have Firefox 95.2.0 (2012-12-16) on my phone. And I have 95.0.2 on my desktop. Everything on mobile marked to synchronize. I've even manually clicked "sync"... Phone says everything was uploaded. But nothing is in the list on the desktop. When I tries to add a "new device" in preferences on desktop, I expect it to give me QR code. But it gives me instantly "Synchronization failed" instead. I'm tired to open list on phone and then type everything in on desktop. How can I fix the issue?

Hello,

I try to sync with my work computer (windows 10) but nothing is imported. No bookmark, no password, nothing. I do not have any error message it seems.

What information could be useful to resolve this problem ? thank in advance.

Hi, I have an old computer which I have Firefox on with tons of stuff...after getting a new laptop and syncing the two I want to now delete Firefox from the old laptop and use it for other things and still have all the old stuff on the new laptop. I thought the server keeps everything and if I sign out the old laptop that whatever was saved in to the new laptop stays. However, on the new laptop after signing off the old one from sync I don't see the tabs anymore. It makes sense because there is nothing to sync but how do I do what I want then? Many thanks for your assistance. Do I have to "send" 1000 tabs from old to new? Isn't the server maintaining the tabs/history even after I sign off the old laptop from sync?

Many thanks in advance for your assitance.

I have two desktops that we use on a daily basis, both have Firefox sync turned on to sync bookmarks, addresses, add-ons and settings. I also have a laptop that I use sporadically, maybe once every two-three weeks, or longer. It also has the same sync settings. Here is the issue I'm having with sync. When either desktop has new bookmarks added/removed they always sync perfectly to each other (desktops). But, if I turn my laptop on after a couple of weeks of being off, then it always syncs the 'old' bookmarks (up) and then the desktops get synced (down) with old bookmarks. How can I prevent this from happening and does anyone know why, in this scenario, it is happening? I've checked various places in settings and cannot find anything obvious to fix this. All devices, laptops & desktops, are very regularly updated with the most current firefox version, except on occasion if the laptop has been off for a couple of weeks or more, but once it's turned on, it updates.

i use firefox on both my desktop (windows) and laptop (macbook). I try to sync the 2 so that the logins (passwords saved) on firefox desktop but although i am logged in and synced in firefox macbook (bookmarks have been synced) the saved logins dont. The firefox macbook saved logins are empty. I tried exporting them in csv from the desktop and import them in macbook but it shows an error. i even tried to manually save a login in macbook (in the lockwise section of logins) and still shows an error.

thanks

I would prefer to be using Firefox rather than Google Chrome, but, my devices when all being logged in with the same account will not all sync as they should be. They will also be synced, but then they would loose their connection with the other ones. The sync should be that when I would simply log into the browser that it would automatically sync using the login information the same easy way it is done in Chrome. I have kept using Chrome, because of the fact that the sync is able to work across all devices simply by logging in for the sync to work & it will work properly to where all of the browsers that would be logged in would be synced, no issues whatsoever. How can I actually login to the sync on everything with there not being any issues of any kind across all devices?

I'm running version v92.0 (64) on ubuntu 21.04. Firefox would crash upon opening when signed in. It would stay active enough for me to disable the extensions & themes. After doing that it still crashed. I tried going into Troubleshooting mode and it would still crash. I went into Troubleshooting mode and did a refresh. It was still crashing. Finally I signed out of my mozilla sync account and the browser has stayed active long enough for me to type this report.

I've submitted all crash reports in about:crashes, and I'm not really sure what to do next.

Perhaps a local version of the Mozilla Sync profile has been corrupted? if so, is there a way to remove it and pull down the "sync"ed version from Mozilla's servers? What if the version on Mozilla's server's has been corrupted? should I back up the local profile (wherever it is) before removing?

I hope I've given enough information. Please let me know if you need further, more specific information.

Hi everyone,

Every morning when i start firefox i have problem like picture attach.

I try remove firefox and reinstall but not fix.

How do i do for fix?

I'm trying to log out old and duplicate accounts from my firefox account list, I've managed to logout from all of those except 2 old account, if I press "sign out" button and enter the reason why I'm doing that it simply doesn't work, no errors no anything, it'll just stay there. any fix?

On my device list I can see old PCs which don´t exist anymore, but clicking the "sign out" button doesn´t sign them out. What can I do to remove these old devices from the sync-list ?
