Hi, I accidentally did a refresh on my Firefox (Win 11) and therefore I now have an "Old Firefox Data" folder on my desktop and Firefox is completely almost back to stock.

I have lost all extensions, customizations, settings and other configurations. Luckily, I had taken a backup of my bookmarks prior to doing this.

How do I return everything (including extensions) back to pre-refresh state?

Thank you.

i had setup a new windows and when i tried to sync my Firefox data i found nothing and all my bookmarks and passwords was lost.

i need you support to recover my data.

Bonjour, j'utilise un compte firefox depuis longtemps avec toutes mes données, compte mots de passe, favoris, j'ai changé d'appareil et me suis connecté a ce compte, mais cette fois si, je n'ai plus rien du tout, j'ai l'habitude pourtant de changer régulièrement d'appareil et tout se synchronise a chaque fois, mais la rien, je n'ai plus rien, merci de m'aider rapidement

I want to delete certain bookmarks but they keep reappearing. I guess it is an issue with synchronization or something. But I cannot find the right options to solve this. I use firefox on my pc and iphone.

I was setting up a new (desktop) device with sync, and was shocked to realize, that some items are missing from the passwords and settings. It seams like we are in a state of some months in the past. I have checked the about:sync-log and I see a lot of lines like this "WARN DATA LOSS: Both local and remote changes to record".

How is this possible? Can I do something to restore my latest data?

Thanks!

Совершил переустановку Win10. Установил Firefox, вошёл в аккаунт, но ничего не синхронизировалось, как раньше. Сейчас у меня пропали все закладки, пароли и так далее. На кнопку ручной синхронизации нажимал, Firefox переустанавливал.

Hi,

So I reinstall my PC. As I remember, I never before do anything with passwords and bookmarks. Maybe I am wrong, but I was think about to this is all on my Mozilla Account. Now when I look, its probably not. So for my "luck" I have all passwords and bookmarks and history on my smartphone but I have one crazy problem. When I try to login on my mozilla account none of passwords I know doesn't work, so I change password and now when I log in my account with new password doesn't sync anything from my smartphone, but my smartphone also won't sync anything because of changed password. If I log out from my smartphone and log in again with new password, do I lost all settings, passwords, bookmarks and other stuff?

Is there any way to recover my bookmarks and tabs? Everything gone when I logged into my 2017 iMac Ventura 13.7.1. THis happened a few years ago as well. For Command Shift T - what needs to be "open" when i try this? Technically deficient, I am.
