Web Browser Showdown: Safari vs Chrome vs Brave vs Edge vs Firefox

In this article, I will compare the main and most popular browsers. I know there are more (Vivaldi, Opera, Arc, etc.), but I wanted to focus on the most popular ones to avoid making the article too long.

The versions tested are as follows:

• Safari 17.4
• Chrome 123
• Brave 1.64 (Chromium 123)
• Edge 122
• Firefox 124

First, I will test the supported features of HTML5 using the html5test.com website and summarize the differences. Differences in features that have been rejected or replaced by more modern ones will be ignored.

Then, with YouTube loaded, I’ll look at the memory each browser is using with all extensions disabled.

Let’s go!

Memory consumption after loading YouTube

In this test I open the YouTube trending page, rejecting all cookies, in a private window with all extensions disabled.

On Windows I have excluded Chrome, because my system is ARM and there is not a stable version for ARM yet.

I’m surprised to see the difference in memory consumption between macOS and Windows. I don’t know why. They are very different systems, and in the end, all browsers work well on both systems, but the numbers are twice as high on macOS.

On the other hand, the consumption is very stable in macOS, while on Windows, a process can use 300 MB and, in a few seconds, jump to double, then go down a little, then go up again, etc. I found it easy to get an average in macOS, but on Windows, they are very changeable values. So after about 10 seconds, I wrote down the average value that seemed more stable to me.

Conclusion

One browser has come out the clear winner in both tests: Chrome. Although it has the same score in HTML5, its memory consumption is lower. So, if you want the best browser based on Chromium, with the Blink engine developed by Google, Meta, Microsoft, Opera, Adobe, Intel, IBM, and Samsung, that browser is Chrome.

If ad blocking is very important to you, instead of installing an extension, I recommend Brave, which already integrates this functionality, and you will save memory.

Edge is a unique option, being ideal if you use Microsoft services. It has unique options, such as Bing Chat support or screen splitting to load two websites in the same tab.

Safari keeps up quite well, rubbing shoulders with Chromium-based browsers. Remember that Safari is the only one that integrates with iCloud+ if you are in the Apple ecosystem and pay for this service.

With its Gecko engine, Firefox is the lowest rated in the HTML5 test. It also consumes the highest amount of memory on macOS.
