How to install Zen Browser on Arch

There are 3 aur packages

https://aur.archlinux.org/packages?O=0&SeB=nd&K=zen-browser&outdated=&SB=p&SO=d&PP=50&submit=Go

Generally you have 2 options

• with avx2 - faster rendering but required modern cpu
• without avx2 - higher compatibility
• private-window-launcher - we will not cover this package

What avx2 is?

AVX2, or Advanced Vector Extensions 2, is an instruction set that enhances CPU performance by enabling parallel processing for tasks involving large datasets, like numerical simulations and multimedia applications, by operating on multiple data points in a single instruction.

AVX2 typically shines in tasks with high data parallelism, such as video playback, image processing, and JavaScript-heavy sites. For these tasks, AVX2 can provide a 10-30% performance boost over non-AVX2 workloads, sometimes even higher for highly optimized algorithms.

In real-world web browsing, the AVX2 gain might be lower because only some parts of a browser’s workload (like rendering and media decoding) are AVX2-optimized.

Check your cpu avx2 support

lscpu | grep avx2

if you see flags like avx2 you can install zen-browser with avx2 support

yay -S zen-browser-avx2-bin

in other case:

yay -S zen-browser-bin
