Firefox for Android Community Forum

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. 😳

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.

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.

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.
