Inbrowser problem

I've been playing minecraft on the Internet browser untill recently when I try to launch minecraft on it it just shows a white screen. Does anyone know how to fix it?

Another question I wanted to ask was about the downloadable laugher giving me a "java could not create the virtual
Machine" or something like that.

Thanks in advance:D

Have you tried updating your Java's?

Well you should maybe check your java preferences to make sure that you have the most recent or best one on top.
And also my sibgleplayer isn't working on 1.8 idk why... So maybe that might have something to do with it.

And albuce if you wouldn't mind, could you put your signature thing in a spoiler because sometimes my family comes over by computer and idk what my mom or younger siblings would think of it.

Yeah I just updated java but it seems to keep happening. I am now trying to delete my minecraft folder but i forgot how to find it in appdata(hidden folder).
Any idea on how to change the search settings ?

minecraft folder is located in (on windows): %appdata%/.minecraft

Or, you know..Just download the actual client. But your computer may be to laggy if you're playing on a web browser.

Sorry, I spelled launcher laugher(iPod keyboard lol)
Anyway When I download the launcher, it says 'java could not open the virtual machine' know how to fix that?
