A quite unprofessional test of browsers. Normies like you and me will have this much more relevant than professional tests anyways. An hour of copyrights and boring content. Here is the short for the 6-tab Danbooru test on stock Debian settings (fresh install of each browser) :

CPU : 5600X Single-Core Two Thread (60-70 GFLOPS)
RAM at startup : 1.8GB Max
HDD : Forgot to show
GPU : No need to show : GPU Acceleration : Unknown for video.
Browser shutdown : 1.7GB/1.8GB RAM Restored.

Google-Chrome-Stable (103) : 0.4GB/1.8GB Used (1.4GB/1.8GB Max), CPU Power : 6.2 - 20% (50%-60% during page loads)

Ungoogled-Chromium (103) : 0.3GB/1.8GB Used (1.5GB/1.8GB Max), CPU Power : 3.2% - 6.2% - 9.6% - 10% - 18.7% (46%-77% during page loads)

Epiphany Browser (WebKitGTK-2x) : 0.7-0.8GB/1.8GB Used (1.0-1.1GB Max), CPU Power : 6.4% - 9.6% - 13% - 29% (53% - 56% - 71% during page loads)

Opera-Nonfree : 0.4GB/1.8GB (1.4GB/1.8GB Max), CPU Power : 10% - 15% - 25% (30% - 54% Max)

Midori 7 : 1.0GB/1.8GB (0.8GB/1.8GB Max), CPU Power : 6.6% - 20% - 35% - 93% (40% - 43% - 57% - 71% Max)

Vivaldi 5.3 : 0.5GB/1.8GB (1.3GB/1.8GB Max), CPU Power : 3.2% - 6.5% - 13% - 19% - 28% (33% - 42% - 60% - 79% Max)

Pale Moon 31 : 0.8GB/1.8GB (1.0GB/1.8GB Max), CPU Power : 6.5% - 9.3% - 16% - 31% (48% - 53% - (+75%) Max

Firefox 103 : 0.6GB/1.8GB (1.2GB/1.8GB Max), CPU Power : 3.1% - 6.6% - 9.3% - 21% + (36% Max) ( 38% - 46% - 60% - 67% - 81% Max)

Yes, this took two hours because I don't know how to test a browser. Frankly, the CPU usage doesn't even matter on a 60GFLOPS CPU because loading a page with any of those browsers aren't even able to max out beyond 80% maximum. However, I noticed Opera generally has a lower CPU usage, with more 30-ish % instead of 40-50%.
I know WebKitGTK can play videos, but maybe my version here is outdated or something since if I install every libgstreamer library, it still fails to work. Browser CPU tests only work well on slower CPUs at 10GFLOPS or so.

RAM Wise, it appears to me that Ungoogled Chromium only uses 0.3GB compared to the other browsers. Midori, Pale Moon, and Epiphany despite being lightweight browsers use a massive 1GB or so of RAM. Firefox is right in between.
