Firefox gives you more privacy but at the cost of fewer extensions and some sites not displaying right compared to Chromium.

Only use Chromium if you want to tinker with the raw browser code; for anything else, Firefox is the more practical pick between these two.

If you care about using browser extensions and having websites work exactly as intended, Chromium is far ahead. All the major browsers people actually use (like Chrome, Arc, Brave, and Edge) are built on Chromium, so you get the full set of Chrome extensions and basically never run into weird compatibility issues. Switching between Chromium browsers is simple, and your extensions, bookmarks, and features just carry over.

Firefox, on the other hand, is all about privacy and not being tied to Google, but you pay for that with a much smaller extension library and a higher chance that sites break or don't look right. Since Firefox runs on its own engine and has a tiny share of the market, web developers just don't prioritize it. Most people who try Firefox end up keeping a Chromium-based browser around anyway for stuff that doesn't work.

So if you want everything to just work and need access to all the extensions everyone else uses, Chromium (or any browser built on it) is the way to go. Firefox is only worth it if you're willing to trade off convenience and compatibility for privacy, and even then, you'll probably need a backup browser.

Firefox Editor's Verdict

User Experience

Firefox sets itself apart with a privacy-focused approach, but you immediately run into friction from its limited extension support and lower compatibility with websites. You lose access to the huge ecosystem of Chrome extensions, unless developers specifically rebuild them for Firefox, which rarely happens. That means you're stuck with fewer options, and there's a real chance that some sites simply won't work right.

If you pick Firefox as your main browser, you'll probably find yourself reaching for a second browser just to get full features or to use sites that don't play nice. The interface doesn't get in your way, but the constant need to switch browsers or deal with missing tools breaks any sense of a truly efficient or seamless workflow. You can get by, but it never feels smooth or fully reliable for heavy or demanding use.

Chromium Editor's Verdict

What is Chromium?

Chromium is something you're likely using right now without even realizing it. Are you using Arc Browser, Chrome, Brave, or even Microsoft Edge right now? Okay, then you're using Chromium.

You know those extensions you have in the top-right corner? Yep, those are Chromium extensions (often referred to as "Chrome Extensions"). Little do people know, Google built an open-source foundation to the browser, for which most of the top browsers on the market use as their foundation.

Competition

I mean you're not exactly looking at traditional competition here, but Apple does use a competing standard called Webkit. So if you're using Safari on your computer, that's running on Webkit instead of Chromium.

The super interesting part here though is if you're using iOS, any browser you're using is actually built atop Webkit—even Google Chrome. Apple requires Webkit be used on iOS regardless.

Why exactly? Well, Google pays Apple some $20bn per year to be the default search engine in Safari, so holding onto Webkit on iOS and iPad is probably one of their leverage points:

“At-least we still own the foundation of the browser for our products!”
-Apple (probably) 🤷

Final Verdict

This genuinely probably doesn't mean much to you, but you're probably using Chromium and you probably don't care.

Just know that it makes for switching between Chromium-based browsers far easier—from transferring bookmarks, to extensions, and everything inbetween.
