WebGL Memory Error when loading asset bundle

My app works fine in the editor., When I run it in a browser however it fails when it tries to load my AssetBundle. Firefox gives me the most useful response which is the error message attached below.

My asset bundle isnt particularly large, maybe a few dozen models mostly under 100 tris and associated textures.

I can't find any setting for WebGL memory as the error messages suggests in the player build settings. What can I do to clear this up?

Thanks
