6 years ago Hey Brent,
I haven’t observed stark differences in performance across browsers.
I’m not sure what could be causing the slow downs, but a community member did point out that the scroll event listeners are not passive (#416). This could be something to explore on your own, but definitely something that will soon see its way into a future release.
Did you run the browsers performance profiler on your page? Also @brentbarkley, could you see if upgrading to ScrollReveal 4 has any impact?
OSX Firefox 61.0.1 ScrollReveal 3.4.0
After adding a relatively simple SR request, the whole page is just jerky/jumpy/sticky when scrolling. SR ultimately works, but the performance is poor. If I remove SR, page performs fine. Note: only in Firefox--other browsers perform well!
Did my homework and didn't find anything helpful through an hour of investigating. Is this a known problem with Firefox or is it likely related to some conflict/code in our site? Can share a link to our dev site privately, but would rather not here. Just looking for a hint of where I might need to look to address a browser-specific performance issue like this.
