Hey Firefox users, this guide will help you never [ctrl] + [W] too many times and close mg. For starters, if you don't have Firefox, I recommend you get it, it's faster than any other browser and has hundreds of thousands of addons/themes.
So after you've got Firefox installed, you can first go to mg, which you're probably already on. Go up to your tab that has a little skull on it and right click. Then click "Pin as app tab" as shown below.
Now you should see it as just a skull, no words or anything (See below). You won't be able to [ctrl] + [W] and accidentally close too many tabs now, you'll always have MG open!
