In the past I have found myself working with laptops with few resources and small screen (eeepc). Every pixel gained was a big win, and finding equivalent lightweight, high-performance applications could make all the difference. Eventually I found the optimal solution with i3 as windows manager and alacritty was the best terminal to use together (and zsh). Since then even though I have no real need I have continued to use this approach. And in the end being careful about pc resource consumption is also an ethical choice, if the pc consumes less power it is a gain for the environment.

I see is a alacritty fork. what does it have more?

In my case it's resource consumption, efficiency the impact with the windows manager I use, how much is keyboard controllable. It seems strange to me that a linux user uses the default applications. The beauty of linux is the huge variety and the ability to customize. If you use allova ready-made things, a mac or windows is fine too

icecat is based on the LTS version, iceweasel the rolling-release. I have been using iceweasel for almost a year and all the sites I have used work

nobody uses iceweasel? For those who don't know, it is the version of firefox cleaned up by non ‘libre’ code mainly from debian and then taken over by parabola linux. For me it is the best together with mullvad.
