Warning: This page almost crashed my browser (FireFox on MacOS) and put my CPU on fire.

View on HN

My poor 2015 MacBook Air with FireFox went full 100% CPU on this page, I think it's the gifs.

I think Factorio itself actually runs better on this laptop than that Factorio blog post does.

I have a dual-core 2015 Macbook Pro running FF too. htop showed my cpu pinned at 100%, VTDecoderXPCService was taking the lions share, there probably is something weird about the gifs.

the "gifs" all appear to be mp4 <video> elements, not actual gifs. Possibly FF is doing something weird here (such as playing videos that aren't visible), possibly it comes down to whether or not the hardware decoding can handle it or if it's falling back to CPU decoding.

I'm also using Firefox on Mac and had no issues. I'm blocking their Javascript though.

There doesn't seem to be any meaningful JS on the page. A single google analytics script and a tiny[0] little toy script for doing a silly animation when you click on the #rocket element.

Possibly the google analytics is doing something heavy (although it doesn't look to be when spot checking with a profiler), but there's otherwise nothing JS that runs continuously.

Strange. I'm using firefox on windows and didn't notice any problems.

Firefox @ Linux, also no problems (and a crappy cpu at that). I've noticed some of their very-gif-heavy posts slowing down this laptop before, but not this post.

Likewise (Firefox 89.0.1 on macOS 10.14.6) I had to close the page once I'd scrolled down to the layout of the various building interfaces; ended up just reading the HTML.

Same, this page hangs entire Firefox on macOS
