Hi all, Starting at the weekend or end of last week I think, when I send tabs to another device when that device is switched off then when I open Firefox on the other device, the sent tabs are loaded in private browsing windows, not the main window with my saved tabs in. Sometimes all sent tabs arrive in one private browsing window, sometimes in one private browsing window for each tab. As I can't drag private tabs into the main window this is really annoying! How can I stop this happening please? Cheers :)

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?

Hey mozilla team,

I have issues with firefox sync as it doesn't sync old search history. Firefox Sync works perfectly for recent search history and chronic, but I imported an old profile (xyz.default) to firefox and logged in with my mozilla account. Started synching so that the old profile's history gets merged with the current one. It doesn't. I can see it in the imported old profile, but if I check history on another device, it's not there (aka only locally but not synced yet).

Is it generally possible to add an existing profile and then syncing it to merge it with the current search history one?

Hello,

I actually noticed earlier that, on Android, Firefox was saying the last sync was 11 hours ago. I tried to sync but it didn't do anything, as if the button wasn't there at all. I tried restarting my phone, disconnecting firefox on my phone from my computer, disconnecting firefox on my computer from my phone and all these things did was that, now, it says it had never sync.

I'm a bit lost, I didn't find any solution for that.

Collections bookmarks on the Firefox for Android homepage. I have Firefox sync. I have many regular bookmarks. Collections bookmarks from Android or obviously not available or synced with my Firefox for desktop. Are they synced or backed up at all anywhere? I cannot find them other than inside Collections. If I uninstall Firefox on my Android, Google Pixel phone and reinstall it will everything in the homepage collections be lost?

For maybe a few weeks, I can't synchronise my account, I've tried to log out / log in multiple times but the "Synchronise now" button does nothing and the "Sync" one on the devices tabs just get stuck on "Synchronising..." but eventually does nothing. I can send a tab to Firefox desktop, but that's all. Both devices are logged on my account. I can't choose what to synchronise because it's greyed out.

Hello everyone, my name is Francesco and I have a big problem that I can't solve in any way! I just can’t seem to solve a synchronization issue between two Firefox 135.0.1 (64-bit) installations on a Laptop and a PC (both running Linux Mint 22) and a Firefox 135.0.1 (Build #2016074239) on Android. Can someone please help me? I'm desperate!

Let’s start from the beginning: For a very long time, every time I connected to the internet with Firefox on my Laptop or mobile, my bookmarks would get completely messed up: folders duplicated endlessly, some empty, others identical to the original ones. The same happened with the bookmarks themselves: separators almost all moved to the bottom and multiple duplicates of my countless bookmarks.

After several failed attempts following posts from other users who had the same or a similar problem, as well as some Firefox support how-tos, I decided to try a different approach, which was also described in a post.

First, after logging out of my account on all three devices, I backed up my bookmarks from my PC in different formats (.html, .json), and after closing Firefox, I also backed up the cookies.sqlite, favicons.sqlite, and places.sqlite files—just in case! Then, I deleted all folders and bookmarks from the other two devices.

I then spent the whole afternoon cleaning up my bookmarks on the PC: removing duplicates and redundant folders, organizing separators and bookmarks the way I wanted, and making new backups as mentioned above. After that, I logged into my account from my mobile, triggered a sync from there, then logged into the other devices and started the synchronization on them as well.

But it didn’t work. 😞

PC and Laptop synced beautifully, everything was perfect, but the mobile, despite showing that it was syncing, remained empty—and still is.

I tried several forced sync methods as suggested in some Firefox how-tos (https://support.mozilla.org/en-US/questions/1482205 and https://support.mozilla.org/en-US/kb/how-set-firefox-sync-firefox-android), and I also followed procedures from other posts where users had similar issues, but nothing worked.

I even tried different approaches: logging out and back in first with my PC, then with my mobile; replacing all bookmarks with the ones I had exported in good condition; checking if there was a new update on Google Play. But my mobile remains completely empty—no bookmarks at all.

So, after more than four hours of trial and error, I'm losing my mind 🤯, and I’m also getting seriously exhausted (it’s now 2 AM, and I’ve been up since 5 AM!).

Does anyone have an idea on how to fix this? A plugin? A folder on the mobile where I can manually place the saved files? Maybe a well-aimed hammer strike in a specific spot on the phone? Anything? At this point, even just a good joke might help me get through the frustration. 😜

Now, I just hope I can get some sleep—I’m so stressed that… 😭

Best regards to all, see you next time, and... good night!

P.S.: Sorry for the long post. 😳

Why don't you allow me to sync by logging in, I log in, you gave me the second authentication (wooow security) to my mail, I copy and paste it and you proceed back to the login page saying incorrect password. great job at forcing to qr code, congratulations.

Hello to all. I am writing to ask for help with sync for Android. I have 2 Samsung devices: my S24, which is my phone, and my Galaxy Tab S10 FE+, which is my tablet. I do have an HP laptop, running Windows 11. That device is fine.

I recently noticed both of my devices had the same model # shown up under my Firefox. {it was my tablet.} Idk why. So I read online, that I should sign out, then sign back in, to fix this. So I signed out on both devices, at the same time. I closed both windows, then I restarted both devices, & then signed back in, at the same time. My S24 is fine, but my S10 FE+ is not. It won't sync. So I repeated the same steps with it, and it still will not sync. So I went to my Mozilla Account, then Connected Services, to see the list of devices. I did note a duplicate device, not sure which one. There was no name. I did sign out of it there, but otherwise, everything else looks good. I also pulled up some articles online & troubleshooted, but again nothing. I'm now doing a hard reboot, which is where I turn it off, then wait for at least 5 minutes. Then I'll turn it back on. Nope, nothing. Does anyone have any suggestions as to how to fix this, please? I have no idea as to how to go around the matter by manually doing everything like once a day. I mean, yikes. Thank you for any help, seriously.

Closing remote tab on smartphone closes immediately this tab on desktop. But opposite way stopped to work since some update: Remote tab closed on desktop still appear on smartphone. Not any action, notification on smartphone as it used to be. Fresh install Firefox for Android, updated Firefox on PC (Windows11).

My account has not been updated since 2023?? Is there something you can do about this? Also there were links I clicked, the questions, and those haven't been updated.

Hi

Firefox has stopped syncing from my android phone. In the 'connected services' section of the account page it shows both my PC and phone connected. On the desktop it shows synchronised frequently updating (e.g. 24 seconds ago) but on phone it shows 'never'. It previously showed last sync as 14 days ago but I relogged (from both devices) to try to fix it. It just so happens that 14 days ago I added a new email address to login with my mozilla account (previous email became secondary), but I have checked and both devices are logged in with updated credentials.

Any ideas other than re-install?

I have tried to synchronize my A8 across devices, but not having any luck.

I have signed out, and paired numerous times, but now it is saying it has never sync'ed.

All other devices are working fine.

I used to browse on Firefox on my iPhone, and when I wanted to delve into a tiny page I would send it to my computer's Firefox. That capability seems to have gone away. Is there still a way to do that? I have tried turning Desktop Site on but that doesn't seem to do anything. Help!

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?
