- jsnell 10y agoI would not be too quick to blame the authors of the website. It seems likely to be the same Firefox bug as all the other cases of HN comments complaining about bad scrolling performance in Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1250947 https://bugzilla.mozilla.org/show_bug.cgi?id=1250947
- pygy_ 10y agoBad link, I'm afraid... It's about a box-shadow glitch.
- jsnell 10y agoIt's the correct link (if you read the last 15 or so comments, it'll be more obvious that there is a performance component to the issue).
- mediumdeviation 10y agoIt seems you're correct. Specifically, disabling this rule from the inspector instantly fixes the performance issue. .widewrapper.main { box-shadow: inset 1px 3px 1px -2px #ababab; }
- harlowja 10y agoSame for me; 46.0.1 windows 7 (if authors care to reproduce).
- fspoon 10y agoPage pinwheels on load for me (FF 46.0.1), OSX
- sashee 10y agoWow, it is indeed slow on Firefox! Thanks for letting us know, we both test on Chrome so we didn't notice the problem. We'll look into it.
- LnxPrgr3 10y agoI loaded this in Firefox on a Raspberry Pi 3 (don't ask), and never got to see below the fold--burned CPU for a minute or two before I gave up and closed it. I had pressed page-down once--don't know if it ever got around to processing the scroll event. Don't know the root cause, but the worst most sites get on here is annoyingly sluggish. Between the site and Firefox, something's definitely triggering pathological behavior.
- anglebracket 10y agoAs a workaround you can go to "View > Page Style > No style". It honestly reads just fine without CSS.
