WEBGL Memory Usage Problem

Hey, we are in the process of exporting our game to WEBGL platform in unity, but have a couple of problems concerning memory usage.
When I open the project in the browser it takes up more 1000MB of memory, then it goes down to 700mb,
when the game is running the memory is increasing.

Memory usage depends on both browser and project. I suggest you read the following blog posts on the topic:

If you have further question you can always ask them in the forum.
