I can partly confirm this odd behavior but it is a bit complex:
create a new trade from chat window --> browser
open a trade a got from someone in the chat window --> browser
new trade offer from profile page --> client
new trade offer via trade link pasted in chat (the one with token) --> client
click on an old trade offer sent to someone in chat window --> client
It's the same experience for me. If it's a plain link, it opens in the client. But if it's the embedded trade offer, it opens in the browser.
I am having this same behaviour on the Windows client, this page is one of the most recent results when I searched for this problem I am having.
i'm having the same issue on arch linux with latest version of steam beta at the time (20dec 2019 version)
Same issue here, also on the Windows Client
Same issue, still persists
still not fixed
3 years, and the same....
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
Any trade offer links will be opened in my main browser instead of the Steam client. This happens in Stable and Beta client as well.
Log says this for each link I click on:
