I would like to join the previous post and add something. I am using sync- function very intensively and I have created my personal order to find any information as fast as possible at every device I am using. Now it seems a litte bit that the order relies on last access. Probably there are some people which like this, but - please - dear mozilla dev-team - can you give me back my own order of bookmarks and make the order by access time a feature?

I just noticed this problem as well, it was normal yesterday December 18 2024. In each folder the order was subfolders at the top, then links in the order they were added in, as in oldest folders then newer folders then older links then newer links. Now they are in some bizarre jumbled order I can't make heads or tails of and I can't re-order them, at least not on mobile. As far as I'm aware the last update to the Firefox app was at least two days ago, so the issue started after it but not immediately afterwards. Some of my folders have dozens of sub-folders and hundreds of links and I can't find anything like this, and it would take me upwards of 3 hours of work - on my desktop, mind you, which may not even have this problem - to get them back to the order I need them in. I can't move bookmarks around in the app - so why did some mysterious force get to move them around in here without my consent? It's vexing.

I have the same issues. my bookmarks are re-ordered after i update firefox android. This is so frustrating 😡

I sincerely apologize for the double post. If you install the latest beta version (at the time I installed it, the version was 135.0b4), your bookmarks will return to normal. I am very disappointed with what happened to the stable version of Firefox for Android.

I'm having this problem. My bookmarks have been rearranged so that whatever has been most recently modified is at the top. It's very difficult to sort through, and there's no option to rearrange.

Version 135.0.1

What is the solution? My bookmarks on Android are now all mixed up, but they remain as I wished them to be on my laptop.

I just found the culprit (for me at least). In Settings > Privacy and Security > Data Collection > Studies I found there was a test update of the bookmark system installed. Deleting it fixed the problem. I suspect this is also why things are changing outside of regular updates.

Turning off studies worked for me. Thanks.
