Just tested yesterday some few more games in browser using Firefox on Mac ( as previously Safari caused some massive memory leak 
on some game )
What this topic is about ?
How to setup webexport template in Godot that will works fine on itch.io
Ok , what I tried ?
Simple 2d platformer , with one level set as opening level , it use mouse and axis x and axis y to jump .
This is done from 4.6 stable release compiled for Apple Silicone only , and templates are downloaded from official mirror .
What went wrong ?
First when tried Thread Support , packed all in zip and of course execute was named index.html only black screen appeared on itch.io and locally.
When turned that off it start load but stop somewhere around half way and staying there .
So this make me wonder , if someone do exports what setting should we use for itch.io to keep it happy .
Also this was help me isolate problem if is browser , compiled version , template , some setting , or other problem .
( Game runs run locally btw )
Ok main difference is you need to switch to Compatibility from Forward+ while export to Web.
