MaterialFox

There are a few, but I'm not sure if they're close enough for you or not: https://addons.mozilla.org/en-US/firefox/addon/google-chrome... Truthfully, I don't think that Firefox and Chromium look all that different, to me it seems like it's the same layout just different margins/colors/tab styles? So I'm not sure what the biggest issues would be to change. Notably, Firefox also has userChrome.css (https://www.userchrome.org/), so if themes aren't able to get you where you want, it's possible that there's a more extensive change that someone has compiled in a user style. https://firefoxcss-store.github.io/index.html, https://github.com/muckSponge/MaterialFox might be good places to start looking, although I don't have personal experience with either source so this isn't a recommendation.

I just use MaterialFox (https://github.com/muckSponge/MaterialFox), which makes Firefox look more or less like Chrome: https://i.imgur.com/gYwrGjK.png Edit: Welp, the new Firefox update kinda broke MaterialFox: https://i.imgur.com/biLz0e2.png

As for the fonts, you can easily change them in the settings. The other nice thing about Firefox is how easy it is to change it's look. I used this https://github.com/muckSponge/MaterialFox for some time to make Firefox look like Chrome (I've been using this https://addons.mozilla.org/en-US/firefox/addon/google-chrome... at the moment), but there are loads more tweaks you can make. There's even a subreddit dedicated to it https://www.reddit.com/r/FirefoxCSS

Try MaterialFox (https://github.com/muckSponge/MaterialFox). It smooths out many of the rough edges that make Firefox feel a bit clunky on macOS.

It's sad because they don't need to. Quantum is great, and you can remap your keybinds and use MaterialFox to get (almost) the exact same experience. Of course your average pleb won't go through this effort, but people need to know how good Firefox has gotten. And to the people who disagree: Firefox has always been great, but it often came with a lot of bugs and inconveniences. It didn't use to be as accessible. https://github.com/muckSponge/MaterialFox
