That's a web site design and architecture issue, not a browser issue. Most web sites are made for Chrome (Chromium-based) browsers, and anything based in Gecko is an afterthought, if anything.
I'd rather just not access a site if Chrome use is mandatory. LibreWolf has been fantastic for me the last 3 years or so. If I really need to access a "Chrome-exclusive" site, I use Brave, and then clear and reset everything in it in case I need it again.
