Firefox Community Forum

I have many computers that I put Firefox on, and had no problem getting my bookmarks on them as long as I sign in to my account. However, I just had my desktop redone (that previously had Firefox) and now, after I have downloaded Firefox, I cant get my bookmarks when I attempt to do the syncing. Please help

I'm still using the old browser because the new browser, the one before that popped up today, doesn't work well on my old desktop computer. New one today requested to move passwords from cvs file and bookmarks from an html file. When I tried to search for these things my computer couldn't find them. But when I went back to the old browser, all bookmarks passwords are there.

Why is Firefox asking me to perform these functions anyway? There is no explanation as to what this is. Is programming at Mozilla really gone downhill so quickly that they forgot how to make their service user friendly?

Dear All, I recently reinstalled Windows and updated to the latest Firefox. When I tried to sign in to sync/restore my bookmarks, Firefox could not recognize my password. I reset it and used the new password, but the bookmarks that appeared were outdated, and not all information synced to my current account.Could you please advise on the steps (or a quick solution) to fix this?Many thanks for your support in advance.Kind regards, Tareq Zeyad

Firefox desktop saved logins not appearing on android. Sync enabled on both devices yesterday. Previously worked fine, kinda frustrating having to manually re enter everything.

I have 2 PCs and one has all my current settings and the other does not. I recently had to re-install Windows 10 and when I installed Firefox again the settings won't sync. Bookmarks, toolbars, etc.

Hi Moz Support,

I've had this happen several times before, but this time it really annoyed me.

I sent tabs from one Firefox instance to another on another device. I closed these tabs on the source device. These tabs were quite old this time, I'd not opened them in a while - this becomes important later.

On the destination device, let's call it "madbilly's destination Firefox", these tabs didn't arrive. After doing a couple of tests where I sent a tab from my mobile to this instance, I realised that this was a similar problem to what I'd had before, which is one where a Firefox instance/profile for some reasons "resets" itself and it seems to create a new instance in Firefox Sync. Tabs which have previously been sent to "madbilly's destination Firefox" don't arrive, because (I think) it's not registered in Firefox Sync as the same instance. These sent tabs, if closed on the source instance (which I did) are lost, unless one reopens the source instance and Ctrl-Shift+T reopens closed tabs. Unfortunately, in this case because the tabs were old and I hadn't opened them for a while there was no way to do this, because Firefox doesn't remember closed tabs which are not stored in memory (another bug, any fix?), except for looking in old session store backups which I'm going to do after I write this post, though I don't know if that will work.

Also, on Android, because it only remembers 10 closed tabs it's not really feasible to retrieve lost sent tabs this way either, and as there's no access to the session store backups the tabs are definitely lost.

Oddly, when this happens "madbilly's destination Firefox" usually appears twice in the send-tab-to menu, but in this case it didn't. To be able to send to this instance I had to sign out of Firefox sync on this instance and sign in again. Then the same instance appeared twice in the sync menu, the old one being now unreachable.

I'd like to know: 1. Why does this happen? 2. How to avoid it happening? 3. Is there a bug registered about this? 4. When will it be fixed and prevented from happening again.

I generally find that this happens when a Firefox instance isn't shut down properly, which on my old desktop I put down to it running out of resources, but on this shiny new laptop from work that doesn't make sense.

All help much appreciated thanks :)

I have a Firefox account. I am logged into my Firefox account on both my desktop and mobile phone. I want to sync them. I cannot do it. I press the three horizontal bars and it does not work.

Three times now this year, I have been automatically signed out of my Firefox account on desktop with no cause. No updates or data clearing to cause it. Every time when I log back in despite having my Firefox synced to my mobile app, my bookmarks & passwords all break. Passwords deleted, bookmarks dysfunctional. I try syncing to restore them. Doesn't work. If I restore from backup, it fixes my bookmarks, but not my passwords.

After the second event like this, I changed my Mozilla password, but seeing as this just occurred a third time this year, that didn't stop it. I reiterate: I DID NOT SIGN MYSELF OUT. I DIDN'T DO DEVICE MAINTENANCE THAT WOULD HAVE SIGNED ME OUT. Sync SHOULD restore these but isn't.

I am using the same account (my school email), and everything else sync successfully.

Tab groups saved on my Windows PC didn't show up on my Macbook; tab groups saved on my Macbook didn't show up on my Win PC. Is this a feature or bug?

I changed my windows and install firefox again, but after I logged to my account I cannot revive my bookmarks and passwords. sync doesn't work for me. I did it several times. but now , it doesn't work.

You need to enable me to sync the desktop to my mobile phone. I've had mozilla firefox on my Mac and android phone for years but now I am expected to work out how to create a back up and then delete all of my data and trust it will upload to the new browser on my desktop -- which before the update held the same data. Really unimpressed. Get it sorted.

I want to "synch"/ export/migrate my current tabs on my old computer to this computer -- the 'synch now' button in your settings doesnt seem to take it on - please let me know?

День добрый. Я с 2023 года не выходил с аккаунта. После переустановки системы, и установки новой версии браузера, синхронизация не подтягивает мои данные (закладки, пароли и тд). Данные очень важны, мне остро необходимо их вернуть.

this is my back-up laptop, which until recently synced perfectly with the main one. now all bookmarks are missing, and I cannot understand what is happening the background.

Sehr geehrtes Support-Team,

ich habe seit Kurzem ein Problem mit Firefox auf meinem PC. Es erscheint folgende Fehlermeldung:

   „Das Lesezeichen- und Chronik-System wird nicht funktionieren, da eine der Dateien von Firefox von einer anderen Anwendung verwendet wird. Dieses Problem könnte von einer Sicherheitssoftware verursacht werden, beispielsweise von einem Virenscanner.“

Ich nutze dasselbe Firefox-Konto auf meinem Handy und auf meinem iPad. Dort funktioniert die Synchronisierung der Lesezeichen ohne Probleme. Das Problem tritt nur auf meinem PC auf.

Ich arbeite bereits seit mehreren Jahren mit Firefox und hatte dieses Problem bisher noch nie. In meinen Lesezeichen sind sehr viele wichtige Webseiten gespeichert, deshalb möchte ich diese auf keinen Fall verlieren.

Können Sie mir bitte mitteilen, wie ich dieses Problem beheben kann, ohne dass meine Lesezeichen verloren gehen?

Vielen Dank für Ihre Unterstützung.

Mit freundlichen Grüßen

Meik

When I frequently turn off my computer using the system unit's power button, meaning a quick shutdown, after several such shutdowns, when I launch the browser, I'm prompted to log in again. Bookmarks that weren't synced disappear. And I'm also logged out of all the websites I was logged into, forcing me to log in again. Cachyos Linux.
