Can I somehow mute the source im recording from for my own headphones while OBS still records the sound from the source?

[Questionsaccount123]

I'm really new with OBS and looked through the FAQ and googled, but I couldn't really find an answer to that question. I want to record a specific window on my PC and have the recording going on in the background. However, I'll be working and listening to something else during that time so I can't really get hear and record everything going on. As an example, I want to record my Firefox Tab, I don't want to hear sound from that tab "live" while recording and don't want to record sound coming from any other window, however I still want to hear that sound coming from everything else on my desktop. Is this possible in any way?
