Is Firefox tolerable to use on a pi 5 or 500+?

I've found that my Pi 400's built in web browser is almost unusable with bloaty script-heavy sites, so I'm wondering if the Pi 5 or 500+ is any better. There would be an NVMe SSD present if that helps.

If someone has this setup, could they take a look at homedepot.com ? That's a very slow and obnoxious site that I use sometimes, as I do buy some from there when I can't avoid it. I'm ok if it's a bit sluggish but my Pi 400 was near incapable of navitation or loading the page in a reasonable amount of waiting.

Thanks!
