Drag and drop lists stopped working in Firefox

Danja P
June 12, 2025

As of a few days ago, I'm no longer able to drag and drop lists in Firefox - I can still drag and drop cards, though, and I can also drag and drop lists in Chrome, but not in Firefox. I checked that my software is up to date (Firefox 139.0.4 under Mac OS 15.5), cleared cache and cookies, disabled all browser extensions except UBlock Origin, tried using an incognito window. Anyone got any tips how to solve this? I wouldn't like to change browsers, but I use the drag and drop lists feature so much I fear I have no other choice if this doesn't get resolved. Thanks in advance for any help!

Hi Danja , Welcome to the Atlassian Community! I hope you’re enjoying Trello.

I've found that moving checklist items using drag and drop works for me when using Firefox. If you're experiencing issues, could you try disabling all your browser extensions, including uBlock Origin? If the problem persists after doing this, please let us know.

Hi Rodolfo, thanks for your reply! I'm not talking about checklists, though, but about Trello Lists, which I was able to drag around to reorder them before. I could disable UBlock Origin for test purposes, but I'm unwillig to use Firefox without an adblocker, so even if this solves the problem, it won't be a solution on the long run :)

I now disabled UBlock Origin just to test and it still doesn't work :)

Hi @Danja P 

Could you please try again and let us know if it works now? Our team has made some adjustments.

No, it doesn't work (with UBlock enabled). I also changed to Chrome as of yesterday, since it was no longer feasible otherwise.

Hello, today after lunch I noticed my drag and drop stopped working as well, in chrome and in Opera, I'll try it on Edge just to be sure. 

@Rodolfo Moreira any updates today that could affect this?

Hi Rafael, I ran a test on my end but couldn't reproduce the problem, and drag-and-drop worked fine in Chrome. Opera is not one of the supported browsers.

In this situation, I'd recommend trying the browser troubleshooting on this hep doc: https://support.atlassian.com/trello/docs/troubleshooting-browser-issues-with-trello/

Can confirm I'm running into this issue as well. Can't drag and drop list items anymore.

Latest version of Chrome; tried with no extensions enabled. Also tried incognito mode. 

Happening on the Mac app too (latest version), even though that is technically just a wrapper on Chrome/Electron.

If I had to take a guess, it started within the last two weeks.

Hi Brian, thanks for sharing your case as well. I was testing here regarding list items (I understand you're referring to checklist items) and I couldn't reproduce it either. Would you mind sharing a screenshot (please blur the private info from the card) and sharing the steps you are taking?
