Firefox Support Forum

On a legacy iMac with over ten years of Firefox usage, I suddenly cannot sign in. The mac caps out at High Sierra 10.13.6 and I am unable to activate sync. I have tried allowing all cookies, restarting the browser several times, and even explored the config files.... to no avail.

How do I "enable local storage"? that's the error that sync provides me, but there is no option to fix that and all of your help files point me to cookies information (which I have done everything with). There are no actual help files to fix the local storage problem. This is frustrating!

Do I have to uninstall the entire application? If so, how to I preserve my bookmarks and pws without also porting over whatever is broken in the application?

I am a long-time user of Firefox and recently had to re-install the browser on my Laptop. I have the latest version of Firefox on both my Desktop and Laptop and have tried to sync my Desktop Settings (tabs, bookmarks, etc ) to my Laptop such that when I open Firefox on the Laptop it mirrors what I see on my Desktop, but to no avail.

I was using firefox for a while and i have to format my pc because of a problem and when i download it again i sync it something came back but not all of them my passwords mostly came back and all my extensitions also back but i have a lot of container and none of them came back and i sent a mail for you but it was Turkish and i get back replied and support guy said we are only taking message as a English and he said i translated your message and be sure you sync the right account and if is it the right account you can also. If you have another device that does have the data, then you can create a backup and manually restore it following the instructions in this article: that what he said but i dont have and ex data and i want to figure it out is it possible to take my cointainers exactly same because the most important reason of using firefox for me was containers.Have a good day.

i had to rebuild my laptop computer and set up firefox on it, set up/turned on sync and the browser does NOT match the broswer srttings on the desktop where the sync comes from. bookmarked weblink icons only show up when a new tab is opened and vanish once a website is opened, icons for bookmarked weblinks on the bookmarks bar are generic wireframe globe-like-icons only, the custom firefox colour setup i struggled to create over the course of several weeks does not appear at all, nor does the dark theme. how then do i get this to -really- syc???

I received an email suggesting that I update my Firefox or I would lose syncing function. I have two computers. A fairly new iMac Ventura 13.6.8 running Firefox 123.0 64 bit which it says is up to date. But I also have an older iMac OSX 10.11.6 El Capiten running Firefox 78.15.0 ESR. I can't update the OS or Firefox on the old computer. So if I do nothing - will I still be able to sync on the newer Mac. I'm not too worried about the old one - I don't use it much for browsing - more for documents. Thank you. David Rimell

Bonjour Depuis 2 semaines, mon compte firefox a perdu la majorité de mes identifiants et mots de passe qui étaient sauvegardés. mais pas tous... je ne comprends pas pourquoi. Avez vous une explication? C'est très ennuyeux ! :( Merci pour votre aide.

Hi, some years ago sending tabs to a device worked fine, but for some time now it stopped working. Is it just me or is it a general bug? All my devices are listed in my account. It also shows that they are updated frequently. I tried sending from Windows-Firefox to Android-Firefox and back. Nothing worked. What can I do? Best regards, Eric

I have multiple times format pc and then instal firefox and log on in sync and i get back all of my bookmarks and paswords. But today that was not the case.

What i did difrently? I loged in with google account instead of email and password on sync page. (from the begining i newer joined my google email with google account in mozila sync service, i always loged in with email and password.) And somehow mozila created new account which is empty ??? If i log out of firefox sync and log in with email and password then i get again redirected to this new firefox sync account which is joined with a google account. How can i get back my bookmarks and passwords? I waited for one hour and password section in browser is still empty and no bookmarks in browser. :(

My Firefox browser is old, but I can't install new one ex.120 or 115, because I'm not able to work with Terminal. What to do? I do download, but after "unpack" (sorry my English) there is the end of it. I do not know how to install.

Hi

I had to change my operating system. before doing that I made sure I have sync my browser. Now after installation browser and login to my account the sync is not doing what I was hoping for. The sync is just uploading the new configuration to the cloud but it is not downloading all the history and add-ons from a version before OS change. I see it is stored but I don't see any option to load those to the current browser. Please, advise what can I do?

Hi,

I had a new windows installation done without backing up the firefox profile while foolishly resetting the firefox password too without using the recovery key and effectively losing my current data.

Is there anything that could be done to restore the data to my account or is that the end?

Duplicate tab closer closed all tabs that weren't loaded into memory, so how may I restore tabs across all tab groups that were closed as now showing 0 ZERO tabs open in most tab groups!?

I use 1 Firefox account on 3 devices (2 PCs and a smartphone). On the first PC, the number of synchronized passwords is 1126. On the second PC - 135 (similar on a smartphone).

I pressed the "Synchronize" button many times, everything works, new tabs appear, but there are no passwords. What to do? I'm afraid that if I log out of my account on the first PC, I will lose all access forever.

Dear Firefox Officer,

I have been requested by e-mail to update my Firefox 78.15.Oesr (64 bits) before the end of March. Is this update compatible with my MacBookPro5,4 with IOS El Capitan 10.11.6? Please note that I cannot install a more recent IOS. Without updating my present Firefox, would I still have access to all my favorite folders and applications? Thanks for your help. Best regards, Marcel Arnould

Hello. I have been using Firefox as primary browser for long time. Today reinstall my firefox because youtube video not playing sound. But after fresh install and synced account but all my savings are gone. Passwords and bookmarks are missing. PLease help me to recover.

Hello, I am trying to sync my browser data between two computers. On the computer I want the data from I click on "Sign in to Sync". This brings me through a couple menus asking me to sign in with google, and finally sends me to a space to set my password. I already have an account associated with my email and already have a password. I type in my same password again and a red bar with "Unverified Session" appears at the top. I am using the latest version of firefox on windows 11. I do not want to delete my account or make a new one. I have tried as many ways as I can think of to link my existing mozilla account to my browser but it simply will not let me. Another support ticket solved this by creating a new account but I find this solution unsatisfactory.
