Why are (mobile) browsers so big? (lemmy.world)

Why are so many mobile browsers at least 100, if not 200 megabytes in size? Even Firefox Focus which is supposed to be small and, you know, focussed is 85MB big.

The smallest browser I could find was the /e/ Foundation's built-in browser for /e/OS. It's 12MB.

It's kind of between Firefox and Focus in terms of features so why are all other browsers so big? Is there a small version of Firefox for Android?

Edit: I just looked up the /e/ Browser repo on their GitLab and the browser appears to be bigger than the 12MB displayed in App Info. It's about 70MB, so pretty comparable to the other browsers. I was so confused by the size difference but that's cleared up now.

Don’t forget developmental complexity. The real limited resource is developer brain power which is the primary (and legit) reason for most failures to optimize algorithms.

Sometimes the most optimized solution requires a developer with enormous working memory, who can write code nobody else on the team can follow.

I worked on an app as a subcontractor once and this guy had functions generating functions to generate functions. It worked, and it was parsimonious in a way. Like he was optimizing for the bundle size and it was pretty impressive, but I simply couldn’t get anything done because the way it was structured required me to hold like 12 chunks of info in my 7-chunk working memory.

I eventually got some progress but only after I had transferred a significant amount of the code into my long-term memory. (As an autistic my working memory was shit growing up so I learned to use my long term procedural memory as a stand-in for short term memory. Problem is it’s a brittle strategy, doesn’t respond to changes well, and is highly sensitive to what kinds of patterns are used).
