Firefox Support Forum

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."

hi I've made a grave mistake, in a hurry I was in need of something from my mozilla account, so I hastely logged in but couldn't so I changed my password since I had access to my email but I lost all my data.....and I do have my mozilla keys for this account. plz tell me there is a way to recover my data for the love of god btw, I didn't see no warning in the reset my password page about losing my data WTH tnx

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 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 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 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 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?

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 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.

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)
