EDIT: AUG 2025 - THIS SPECIFIC ISSUE IS NOW RESOLVED

ANYTHING SIMILAR YOU ARE EXPERIENCING TODAY IS A DIFFERENT ISSUE

-----------

There is currently a bug that was introduced (Feb 2025) to the steam community market by Valve, where all Firefox based web browsers (and the steam mobile client) cannot list items from any game to the community market

You can bypass this issue by using a chrome based web browser (Chrome, Brave, Opera) or the steam desktop application.

I have been documenting this issue here:

https://gtm.steamproxy.vip/groups/SteamClientBeta/discussions/0/599645521255130025/

Currently valve has to revert / fix the bug they added ~6 days ago for this issue to be resolved.

Did you report the issue to steam support? I am sure they are aware of it, but a good post discussing the issue with them may help them patch it up in the next update patch for steam.

I raised the issue to steam support 4 days ago (Ticket: HT-8T5C-KN5T-KBX9), and it bounced around to the wrong teams, and the CS2 team closed my ticket saying the servers were under high load and to try again later.

I was very expressive and mentioned multiple times that the steam support representative likely missunderstood my issue, and re-clarified myself - but ticket was closed regardless.

I also reached out to Jared Christen (Customer support) via Valves website contact page - listing the problem, and included my failed ticket + other places I have raised the issue - I am yet to hear a response back

it's still not working on 02/27

Still not working on mobile. 2/03/25

The problem is still there for Firefox on my end. I have to use a Chromium browser to list an item on the market.

Same here

still not fixed

Still not fixed 3/03/25

Not fixed 05/03

Issue appears to be resolved now

Thanks to everyone for helping I solved it,you simply can't sell it on steam app on phone,you need to go on phone chrome and open up an non archive page then go to steam ,login and then sell your skins.

The issue was with steam mobile app (and all firefox browsers) and should be fixed now, you don't need to use chrome as a workaround anymore if you don't want to

This issue is fully resolved

i cant put something up for selling in none of those browsers :( not even chromium or the steam client

Sounds like an unrelated issue not attributed to the February 2025 bug this thread was discussing

I just checked, and I can list from TF2 and CS2 from Firefox perfectly fine
