Problem with plugin on Linux (Ubuntu)

Just to make it short, the situation sounds like following:

I've just installed the plugin on my Linux computer, my when i use Arduino Create, it won't recognize the plugin. I really have no idea why. I feel like i've tried everything, but maybe one of your great souls out there can help me?

Hi @LongVanNgo,
have you followed the Getting Started while installing the plugin? What browser are you using?
Thanks
