Diễn đàn hỗ trợ Firefox dành cho Android

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. 😳

Yes i tapped sync and on my mac's firefox, the android device is not even shown .. i can see my windows firefox there and see open tabs from there but not from android

why doens't android firefox sync ?

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 reinstalled the Firefox app on my android phone and I am not able to sync the phone now with my account info and bookmarks. Scanning the barcode to sync from my phone does not work. It does not respond at all. Manually entering my email and password does not work either as it says I have the incorrect password when inputting the code sent by email.
