Hi, I'd like to collect some feedback about the Profiler on WebGL, since occasionally people seem to run into problems. The Unity Profiler works on WebGL, like on the other platforms, but there are a few things to be aware of (from our Manual): The simplest way to profile is to check “Autoconnect Profiler”, then select "Build and Run". Though that's not the only option: you can also Profile previously built WebGL content but, be aware that, this only works if you already deployed for WebGL since you started Unity. In addition, we should mention that the Profiler might not work properly if there is a "zombie" unity process still running from a previous session. So, if you run into issues in trying to use the Profiler, try to close Unity, make sure there are no more Unity processes running (for example, using Task Manager on Windows), then restart Unity. These are just a couple of things to be aware of. So, have you been using the Profiler ? Has it been working fine ?
