Browser used to open URLS in TS3

Hello all, anyone know how I can change the browser to open URLs in teamspeak chat windows? Im using Overwolf which has its own inbuild browser, this used to work earlier when URL clicked, but not anymore , now all links will open in my default win10 browser (firefox). I would need that overwolf browser to open top of game window when I click URL in teamspeak. I had this same problem earlier and got it to work somehow, but cant remember how I did it.

any help? thanks

We always use the Browser set in your Operation system.

Please contact the Overwolf support.
Which Browser opens in 3rd party software is not in our control.
