By faster do you mean faster on performance? Or browsing pages?
Here are some tips that might help you decide.
Chrome is the fastest based on browsing speed and compatibility, but cons are it will eat up the RAM and CPU of your computer. So be sure you have the necessary requirements if you choose this.
Firefox doesn't consume as much RAM and CPU as chrome but is a bit slower in my opinion.
You can also try UC Browser for windows and compare it from chrome.
Hope this helps. :)
