Computer crashes during leaving the computer alone on snap

When ever i try to code something on here, after leaving it alone for a few minutes my computer wont corporate unless I restart it by turning it off then back on. This isn't a bug on snap but it happens when i leave it alone when my browser is on and the website on is snap. can someone on the snap team can fix that? Thank you!

Does it occur on the forum? If not, you should change the category.

Browser and version? Operating system and version?

I have a total of nine Snap! tabs open right now, and my computer is fine.

Also, does your entire computer freeze up, or only your browser?
