I'm looking for advice on optimizing my React project for different web browsers. While it runs smoothly on Chrome, I've noticed that performance significantly drops on Firefox. Are there any tools available that can help with cross-browser optimization? Also, is there documentation on which features perform better on specific browsers, or do I need to identify and fix performance issues on my own? Thanks in advance for your insights!

To optimize for different browsers, you should start by using a profiler to identify what specifically is slowing things down. Each browser may handle certain APIs differently, so what works fast in Chrome might not in Firefox and vice versa. It's all about tracking down those bottlenecks!
Make full use of the performance tab in Firefox's developer tools—it's great for spotting layout thrashing or anything that's blocking rendering. Also, the React DevTools profiler is super useful for seeing which components are re-rendering too much. Often, it's little things like unoptimized images or CSS that Chrome copes with better. Don't overlook those!
Yeah, I just found out about the Firefox performance profile and had React DevTools handy, but I sort of forgot about using them... my bad! But I still wonder if there's a way to test on other browsers without downloading them all.
I'm using that right now, but I don't want to download and check every browser, so I was wondering if there's something that covers all browsers?
