Problem in question is when you have:

• Discord (Electron)
• Slack or Teams whatever
• Steam for DRM (Chrome Embedded Framework)
• The game (Electron)

running all at once. You can just skip Steam and run everything else in one instance of Firefox.

Oh, and let’s not forget the “average person” will also have Spotify (literally just desktop Chrome), the Winsoft from Microdows 11 React Native start menu and the 3 macrohard background Chromium instances from different era embed APIs. Let’s not support it any further.
