Browser Speed Tests: Chrome 24, Firefox 18, Internet Explorer 10, Opera 12.12

Windows 8 is out with a new version of Internet Explorer, Firefox has boosted its JavaScript power and memory usage, and Chrome has been slowly improving its speed. How do the new versions stack up against each other? We found out in our latest round of browser speed tests.


How We Test Web Browsers

Lifehacker regularly runs browser speed tests to see which browser runs the fastest in real-world situations. This is how we currently test browser performance.


Browser Speed Tests: Firefox 7, Chrome 14, Internet Explorer 9 And More

Firefox 7 is set to be released today, and with a big focus on performance, we thought it time for another round of browser speed testing. We pitted the four most popular Windows browsers against each other in a battle of startup times, tab-loading times, JavaScript powers and memory usage, with some surprising results.


Android Faceoff: Which Browser Wins Out On Speed, Features, Usability

One of the many nice things about Android is that you can install your own essential apps, like a browser, as your better default option. But do third-party alternatives like Firefox, Opera or Dolphin actually deliver a better browser? In many cases, yes. Here’s how.


Updated Browser Speed Tests Show IE9 Is Slightly Better

It turns out that Internet Explorer 9, in its 64-bit version, apparently has a different, slower JavaScript engine than its 32-bit counterpart. We didn’t know that when starting our browser tests, but we’ve now updated our tests with IE9 32-bit results, at least in the JavaScript and CSS categories. Doing so gave IE 9 32-bit an edge in at least one category. Thanks to commenters and Twitter correspondents who pointed this out.


Browser Speed Tests: Firefox 4, IE9, Chrome 11 And More

It has been quite a month for browsers, with Internet Explorer and Firefox both dropping big new versions, and Chrome and Opera continuing their regular improvements. We tested all these browsers’ startup and tab-loading times, JavaScript powers, and memory use for your fast-minded enjoyment. Update: With 32-versus-64-bit IE 9 results.

Google’s got a new “Crankshaft” in its bleeding-edge Chrome, Internet Explorer 9 is out to prove its modern mettle, Firefox 4 is nearly complete, and Opera’s adding extensions. It’s a good time to put these browsers head to head.

Testing Suites Show Firefox 4 Not Quite Caught Up In Speed

We ran our own Mac-based performance tests last week with Firefox’s pre-beta release candidate, and found Firefox 4 an improvement, but not quite catching up to other browsers in raw speed.

Many readers have asked us to replicate our browser speed tests on a Mac, to see the difference in platforms and performance. So we snagged a new MacBook Pro when nobody was looking and tested the latest browsers on it.
