Diễn đàn hỗ trợ Firefox

I've had a smooth ride with firefox sync for a few years now and I have admired how quick and safe it has been. I was a long time xmarks user. However today it went off the rails. I booted a virtual machine for the first time in years and while on that vm I used firefox. That copy of firefox had never had sync enabled and the bookmarks were very old. I uncautiously turned sync on, thinking that it'd favor the current bookmarks over years old bookmarks. Nope. Now I find all of my active instances of firefox (all windows flavors) have bookmarks from 2016. Two things.

1. 1 What's the best way to restore my current bookmarks? I have backups from last night and maybe even more recent. I know how to restore bookmarks...but I'm concerned that sync will just repeat the same error and adjust to the 2016 set.
2. 2 How did this happen? I have gotten to trust sync so much that I just enabled on the old firefox without taking any precautions. That was probably a mistake plain and simple - sync is complex and that sort of gap in dates could be unanticipated. But still it seems odd that sync would favor an ancient set over the current set.

Firefox is a great browser and sync is part of that greatness. Thank you mozilla.

hi please help me my bookmarks my passwords and my site settings and...... when i log in my account is not coming i syncing buy is not come please help me is the support of fire fox can't help or can't recovery my information I'm so sorry for all of them

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'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.

I synced my bookmarks and everything on my old computer and when i singin on the new computer and logged in to my firefox it doesnt have a single bookmark or login credentials.

I am switching jobs and want to sync my Firefox history from old work computer to new. Both run Windows. I changed the primary email associated with my account from the old work account to a new email. No problem. I synced the new email to my iphone no problem. Now im trying to download and sync Firefox to my new laptop. Running Windows and Im trapped in a crazy loop. I login with correct password to the new email and it asks for the authorization code and when I enter that, Firefox switches to the OLD email and asks for that password. I am not sure I have that password correct because i set the account up four years ago. Regardless, i cant sync my new laptop. But I was able to sync it on my iphone so it CAN be done with the email addy and password I am confident about. Please help.

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 ?

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.

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?

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 can't sync data from old account, anyone have this problem?

(I changed computers, and I logged into my account on the new computer, but there is absolutely no data that I have synced before)

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'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?

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?

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.

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.

Firefox continiues to wipe all of my saved password and bookmarks. After fresh windows install, I signed into my account and figured out that all of my bookmarks are gone. It happend for the second time. I have a mobile device running firefox which is lincked to my account. It's also gone there. How can I fix it or restore my data?
