What don’t you like about Firefox?

Speaking as a FF user I have a hard time using Chrome too. In other words you get used to what you use and FF is a decent option.

Not the original commenter, but Firefox has noticeably poorer performance on my MacBook pro 2018, especially on react-heavy sites like the AWS Console or Twitch.tv

Mostly this, performance is atrocious on a lot of sites I use.

I also dislike its history management, download management, auto-complete, search in address bar functionality, pocket integration, and much more. I'm sure if I were forced to spend more time with it I could possibly find configurations to customize all those things in a way I like, but even using it for a few days the easily findable settings weren't flexible enough.

I realize your comment says you’ve already switched back, but should you ever try Firefox again most of these can be tweaked directly from about:config

I know, but not enough to my preferences at least from as far as I dug into those settings.

To me Chrome has poorer performance, especially when switching between tabs. I've seen Chrome take minutes to "load" a tab.

Yeah, there's an issue on Mac's with scaled resolutions. Not a problem on other platforms, but not sure why it's so sticky on the Mac.

Firefox has awful performance on nearly any web page for me (2014 Mac). Even its own settings page alone puts a core at 100%. I can get past bad font rendering and giving up pinch-to-zoom and not reading PDFs in the browser, but I can't give Firefox half my battery life. I'll use it on my work PC but it's still a huge waste of electricity.

Huh? I read all my PDFs in firefox.

Both Chrome and Firefox are noticeably heavier than Safari on macOS. The most obvious sign of that is battery usage.

Here’s a tip for saving battery on MacOS:

I also made the switch but firefox is definitely slower than chrome and sometimes it borders on being unusable on some website where chrome's performance was spotless.

Memory usage.

I know everyone says Chrome is a memory hog, but for me Firefox turned out to be even worse. It kept crashing with the same tabs Chrome was running with ease.

I have stuttery performance on mac with firefox.

biggest issue for me is firefox's lack of audio pitch correction on sped up videos. at 3x the audio is unclear; chrome handles it perfectly.

I also prefer Chrome; it has always felt more stable on Mac OSX; I often find myself with 50+ tabs open and it is no issue with Chrome, Firefox can't even come close.

Have you checked out Brave Browser?

Yes. As with firefox, they've made some design/ux decisions I'm not a fan of.
