Is this bad?

1) So I went on to inspect element and i found something weird

2) Then i went on to console and i saw some red tags.

I have an image of proof, it's like some red things on the right hand side of my computer when i first opened the console in the inspect element ( F12 ), I believe it's bad so here is the image:

As you see, there is some red things on my console ( can't explain it ) I believe it's going to crash my computer or maybe lag i don't know. ( I never get lag ), this might harm my PC so if you can fix it that will be awesome.

If you dislike or hate it, comment about what you hate, dislike about it.
