The browser could not allocate enough memory

Unity Engine

Try to allocate less memory.
I allocated 128mb to the game,my release folder is 9mb. And it works well on the chrome,but my friends found that “the brower…” will appear after they play for long time and they can’t open the website any more because of the message(they use firefox)

I use WWW to post form to php and connect mysql, does it influence it?

Other tabs could contribute to running out of browser memory. Can you tell your friends to use a 64-bit browser?

I notice today that with last FireFox (52.0.1), there seems to be a memory leak because if I reload my application mutiple times I get the “out of memory” error.

Chrome and Canary = no issues

Alright, and I have a question that how to allocated appropriate memory?
