Chrome against Firefox on Android
On desktop this comparison is close. On Android it turns on one structural difference: Firefox supports extensions and Chrome does not. Everything else is a matter of degree, and that one thing is a matter of kind.
Where they actually differ
| Chrome | Firefox | |
|---|---|---|
| Extensions | None | A curated set including content blockers |
| Rendering engine | Blink, updated with the system WebView | Gecko, independent of the system |
| Speed on modern hardware | Slightly faster | Close, and closer every year |
| Speed on old hardware | Better | Heavier |
| Tracking protection by default | Basic | Strong |
| Sync | With your Google account | With a Firefox account |
| Data saving | Limited now | Via extensions |

The two, and the alternatives
Extensions, including a proper content blocker, and its own engine. The right default for anyone who wants control over what pages are allowed to do.
Fastest on current hardware, best integration with Android and with Google services. No extensions, which is a deliberate product decision rather than an oversight.
Chromium speed with blocking built in rather than bolted on. The answer for people who want Chrome's rendering and Firefox's filtering.
Simpler than either, with strong tracker blocking and a one-tap clear. Good as a second browser for casual browsing.
Edge, which is Chromium with a built-in blocker and unusually good reading tools.
Opera. Built in advertisement blocking and a free browser VPN.
Vivaldi. Chromium speed with more control over the interface than either browser here.
Kiwi. Chromium with desktop extension support, the closest thing to Firefox add-ons on a Chrome engine.
Samsung Internet. Runs on any Android phone, with content blockers and a secret mode.
Tor Browser. Firefox-based, for when privacy matters more than speed.
Choosing on what you actually do
- You want an ad or content blocker
- Your phone is old
- You dislike sending browsing to a Google account
- You use the same extensions on desktop
- You want the fastest option on a current phone
- You are signed into Google services anyway
- You want the tightest Android integration
- You want a browser you never think about
There is a third answer worth stating: use both. Firefox with a blocker for general browsing, Chrome for the occasional site that behaves badly in anything else. That is less silly than it sounds, and it costs nothing.
Settings worth changing in either
- Turn on HTTPS-only mode Both offer it. It costs nothing and closes a real gap.
- Set search to something you are comfortable with The default is a business arrangement, not a recommendation.
- Turn off search and site suggestions They send what you type before you press enter.
- Enable enhanced tracking protection On by default in Firefox, worth checking the level in both.
- Turn on encrypted DNS at the system level Covers every app rather than just the browser.
Firefox if you want a content blocker or your phone is old. Chrome if you want the fastest default and do not care about extensions.
Frequently asked questions
Can I use extensions in Chrome for Android?
No. Google has not implemented extension support on Android and shows no sign of doing so.
Which browser is faster?
Chrome, marginally, on current hardware. With a content blocker installed, Firefox often loads pages faster because it fetches less.
Does Firefox use more battery?
Somewhat, historically. Blocking trackers offsets a good deal of it by reducing background requests.

Nothing has infected your phone. Something you installed has permission, and the fix is a list in settings.
A phone will happily run a keyboard, a mouse and a memory stick. It will not power a desktop hard drive.
Hard and fast are different things. Almost every game confuses them, and these do not.
