Arkenfox webGL but only for itch.io games?

So I use the default everything for arkenfox and while I am okay generally with blocking webGL most of the simple games I would play seem to be webGL. As the firefox I primarily use does not well support multiple profiles I wonder as a question if there is a URL type filter to allow webGL for certain sites

Perhaps just use Mullvad as your main and Firefox with Arkenfox set not as strict for this?

Or just enable WebGL by default and control it via NoScript.

This is the firefox I use on my travel laptop

RBI allows me to remove threats to windows because it is ubuntu VPS hosted

This problem is normally solved by a separate profile. You can make a copy of the Docker container and run it with another configuration.
