Very bad graphics quality and terrible looking shadows in WebGL build

Is it normal that WebGL build of my game looks much worse compared to Web Player build? In WebGL point lights don’t work and shadows are much worse. Is there any way to fix it? In my project settings I have the quality set to fantastic for both. I tested both in Firefox 46 . Before I updated to Unity 3.5.1f it was much worse.

I just downloaded Unity 5.4 beta and everything (shadows, fonts, anti aliasing and point lights) now works properly and looks the way it should. I guess updating to Unity 5.4 is the only way to solve this problem.
