Popularity-wise Chrome beats out every other web browser, including Firefox. But it wasn’t always like that. Chrome and Firefox have been around for what feels like forever in internet years. But Firefox launched first in 2004. It was a spiritual successor to Netscape Navigator and a solid, fast, open-source competition to Internet Explorer. Then in 2008, we got Chrome. Google’s shiny, minimalist browser that promised speed and simplicity.
And it delivered. Over the years Chrome’s user base grew and grew. It wasn’t long before Chrome outpaced everyone else, including Firefox, and became the most used browser in the world. Today it has a massive lead in market share. But popularity isn’t everything. While Chrome caters to most users, it still leaves a lot to be desired. And Firefox fills in a lot of those gaps.
In our in-depth comparison, we will be pitting these two browsers against each other in terms of speed, user experience, privacy, and more.

Speed & Performance
Which Web Browser is Faster: Firefox or Chrome?
Both Firefox and Chrome are really fast. So benchmark scores only show minimal differences which rarely reflect in real world usage. We tested the browsers on Speedometer 3.0. Chrome scored 22.5 on Windows and 29.2 on macOS. Firefox scored 18.1 on Windows and a whopping 33.9 on macOS.
All browsers perform better on macOS than Windows. And you can see that it reflects on the scores of all the browsers we tested on Fastest Browsers in 2025. However, Firefox on macOS performs significantly better than all Chromium based browsers. It’s almost as fast as Safari and Orion. During usage, it feels snappy. It can load up pages very quickly. And as mentioned before, the real-world performance for the most case is not that different from Chrome.
However, in day-to-day browsing, some things cannot be ignored. All Google services work better on Google Chrome as expected. So if your browsing and workload depends heavily on Google Workspace tools like Drive, Gmail, and Google Docs, you may want to use Chrome, even though it’s slower on macOS. And that’s no surprise, Google optimises their web apps especially for Chrome. Moreover, Chrome’s browsing speed is also more consistent across platforms compared to Firefox.
Does Chrome use more RAM than Firefox?
Yes. Chrome is really bad with memory management. But it’s also for a good reason (maybe?). So Chrome has this multi-process architecture. Which means it runs every tab, extension and background tasks as a separate process. If you check your Task Manager (Windows) or Activity Monitor (macOS) while running Chrome, you will see that there are multiple instances of Chrome running on your system pretty much all the time. And it’s great for stability. If a tab or an extension crashes, it does not affect any other tasks. However, it also means running more than a few tabs on Chrome can make your system take a noticeable performance hit.
Firefox handles things much differently here. It has a better memory management system that keeps things more efficient. If you’re a tab hoarder, Firefox might be a better choice. Or you can try Zen Browser, a Firefox fork with vertical tabs. It’s better for tab hoarding. But back to the topic on hand, Firefox is very lightweight compared to Chrome and it’s one of its biggest selling points. It runs great on macOS and Linux. And it’s not that bad on Windows either, if you can excuse the low score on Speedometer 3.0.
Which Browser is Best for Battery Life: Chrome or Firefox?
Battery life is one of those things that doesn’t get talked about enough, until your laptop hits 5% during a Zoom call. And web browsers are some of the biggest power hogs on any device. Chrome, unfortunately, isn’t the best at this.
Google has improved Chrome’s battery life in recent updates. And there’s a new Battery Saver feature that has also been adopted to other Chromium based browsers. Like Energy Saver on Arc. However, it still draws more power than Firefox. That’s mostly due to Chrome’s multi-process architecture and background syncing. It’s always running little tasks in the background helpful for real-time syncing, but not so great for your battery.
Firefox is more power efficient. It doesn’t run as many processes in parallel and is better at unloading inactive tabs. On Windows laptops and Linux machines, Firefox lasts longer on battery. On macOS, the difference is smaller, but Firefox still holds its own well, especially if you’re not doing much.
User Interface & Experience
Which Browser Provides a Better User Experience: Firefox or Chrome?
When it comes to out of the box usability, Chrome takes the lead mainly because it plays it safe. It’s clean, familiar, and consistent across all platforms. If you’ve used Chrome once you already know your way around it. The layout is predictable, everything is where you expect it to be. Search bar at the top, tabs stacked neatly, settings easy to find. Even though Chrome has had many visual updates over the years, the core UI elements have always functioned the same way. Moreover, its deep integration with Google services also makes it super convenient. Log into your Google account and everything syncs. Bookmarks, history, passwords, extensions. That’s what keeps most people coming back.
Firefox is also intuitive but has a slightly steeper learning curve. The Firefox UI actually looks more modern than Chrome. There’s smooth animations, readable fonts, and you can even switch to compact mode. There’s a lot more features hidden in about:config, that can change the UI significantly. This flexibility can also be a double edged sword. It might be great for power users, but regular users prefer a simpler out of the box experience. And Chrome really has that done right.
How much can you customise Chrome and Firefox?
Chrome’s customisation is basic. You can change the New Tab page background, install themes from the Chrome Web Store and enable or disable a few UI features via Chrome flags. But that’s it. Google keeps things locked down to preserve consistency and prevent breakage.
Firefox, on the other hand, is a tweaker’s playground. It has deep native theming options that go far beyond colour palettes. There’s compact mode, full theme support and UI tweaks built into the settings. If you want to go further, Firefox lets you access about:config. From there, you can tweak tab behaviour, modify scroll physics or disable certain animations. And that’s just the start. Firefox allows you to edit userChrome.css and userContent.css which means you can write your own CSS to style the browser’s UI and websites. Want a vertical tab sidebar? There’s an extension for that. Prefer to hide all buttons and keep only the address bar? You can do that too. The level of control is unmatched.
Extensions & Add-Ons
Which Browser Has Better Extensions: Chrome or Firefox?
Chrome’s Web Store is huge. By far the largest extension library for any browser. If there’s a browser extension for something, it probably launched on Chrome first. Password managers, VPNs, AI chatbots, productivity tools, Chrome has it all. But size doesn’t always mean quality.
Firefox’s extension library is smaller, but shaped by its privacy-focused users. As a result you’ll find more tools focused on privacy, security and ethical browsing. Developers building for Firefox tend to prioritise transparency and keep their projects open-source.
Manifest V3 and Extensions on Chrome and Firefox
Manifest V3 is Google’s new extension framework that replaces the old Manifest V2 system. Google claims it improves privacy and performance but it severely restricts what extensions can do. Especially ad blockers. Extensions can no longer update blocklists in real-time and have a strict limit on filtering rules. Many privacy extensions had to be rebuilt from scratch to comply with Manifest V3, often with reduced functionality. And some of the extensions stopped working altogether. uBlock Origin, the best ad blocker out there, refused to compromise and is no longer functional on Chrome. But It still works perfectly on Firefox.
Are Extensions On Chrome and Firefox Safe?
Yes, the extensions available on Chrome Web Store and Firefox Add-Ons Store are Safe. Google has some strict extension policies. All Chrome extensions must go through rigorous testing and are reviewed both automated and manual. While that reduces the number of bad extensions, it also creates hurdles for smaller developers. Especially for experimental tools or niche utilities. Firefox’s review process is more community driven and indie-dev friendly, which allows for more flexibility in the types of extensions.
In terms of safety both browsers have checks in place but they approach it differently. Chrome’s automated scans and strict policies reduce the chance of malware but it’s not foolproof. Malware has made it through in the past. Firefox’s approach is a bit more open but the community driven auditing and manual review of recommended extensions creates a layer of trust.
Privacy & Security
Which Browser is Better for Privacy: Chrome or Firefox?
If privacy is your priority, Firefox is the winner here. Not just because we say so, privacy baked into everything you do on Firefox. It blocks third-party trackers by default and doesn’t stop there. It also protects you from social media trackers, cryptominers, and fingerprinting scripts. Its Enhanced Tracking Protection works behind the scenes from the moment you install the browser. Then there’s Total Cookie Protection, which prevents websites from using cookies to track you across different sites. Instead of one big jar of cookies shared across the web, Firefox has a separate jar for each site.
On top of that, it offers first-party extensions like Facebook Container and Multi-Account Containers. These “containers” isolate sites from one another. So Facebook can’t follow you across the internet. It’s a powerful way to segment your online life, and while they need to be installed separately, they’re officially made and maintained by Mozilla.
Chrome, on the other hand, is made by Google, the world’s biggest ad company. That’s the elephant in the room. While Chrome has privacy settings and an incognito mode, its defaults aren’t exactly strict when it comes to privacy. A lot of the browser’s full functionality, like syncing bookmarks and history, requires you to sign into your Google account. Which opens the door to even more data collection. Google is working on privacy initiatives like the Privacy Sandbox, but so far the results are mixed. The move away from third-party cookies is good in theory, but it still consolidates power around Google. If you’re serious about online privacy, Firefox is the way to go.
That said, if you’re comfortable with Chrome and want something more private without leaving the Chromium ecosystem, you could try Brave. You can learn more about it on Brave vs Chrome. It blocks trackers by default and removes a lot of Google’s background tracking. Or you could look into un-Googled Chromium, which is basically Chrome without all the Google services built in. It’s not for everyone, but it’s another option.
Which Browser is More Secure: Chrome or Firefox?
While privacy and security often come hand in hand, they’re not the same thing. Privacy is about controlling who can see your data. Security is about keeping that data safe from malware, phishing and unauthorized access. Both Chrome and Firefox take browser security seriously but in different ways.
Chrome has one of the fastest update cycles in the business. It patches security vulnerabilities as soon as fixes are available. It also has site isolation, sandboxing and Safe Browsing to warn you of malicious sites. Chrome’s multi-process architecture also limits the damage of a single tab or extension being compromised. From a technical standpoint, Google’s security is top notch.
Firefox does a great job too. It has strong sandboxing, regular updates and an HTTPS only mode that ensures your connection is encrypted whenever possible. Firefox also rolled out Total Cookie Protection as a privacy feature with security implications as it limits cross site data leaks. One advantage Firefox has is its open-source security practices. With more eyes on the code, vulnerabilities are more likely to be spotted and fixed quicker.
Cross-Platform Availability & Compatibility
Which Browser Works on More Devices?
Both Chrome and Firefox are available on all major platforms: Windows, macOS, Linux, Android, and iOS. So in terms of availability, there’s no gap. No matter what device you’re on, you can download and use either browser.
But when it comes to syncing and ecosystem integration, Chrome has the edge. If you’re an Android user, Chrome syncs perfectly with your Google account. That means your passwords, autofill data, bookmarks, tabs and browsing history follow you across devices. It’s all tightly integrated into Google’s ecosystem, just like you’d expect.
Firefox doesn’t have a wider ecosystem like Google. There’s no Android OS, no productivity suite, no Google Drive equivalent. But it does offer syncing through a Mozilla account. You can sync your bookmarks, history and passwords just like Chrome, but without all the background Google tracking. Where Firefox has an edge is on Android. Unlike Chrome, Firefox for Android supports extensions. That means you can install privacy tools like uBlock Origin or other powerful add-ons even on mobile, so you have more control over your browser experience than Chrome will ever give you.
Final Verdict
So, Firefox or Chrome? Which one should be on your device? To that I say, why not both? Both of these browsers are free and easy to install. You can try them out for yourself and decide which one works for you the best.
However, if you care about performance, deep customization and above all privacy, Firefox is hard to beat. It’s fast, lightweight and full of thoughtful privacy features right out of the box.
But Chrome still wins for out-of-the-box usability, consistency and convenience. Especially if you’re deep into the Google ecosystem. It acts as a hub for everything Google: Drive, Docs, Photos, Calendar and more. And for many users that level of integration and ease is what makes Chrome hard to leave.
