REAL Firefox Customization

Last updated: Friday. July 7th, 2023 at 07:14 PM

A page about customizing Firefox EXACTLY like how you WANT, because why the hell not? Like being able to actually customize all of the elements of firefox, or at least most as of typing this.

So the thing about user-friendliness

Is that it still tends to be centered around what the devs in charge of incorperating it into something...think...."user-friendly" even means. Seriously. I think that's very clear to be true here. Notice how I say "tend" because of course I don't know everything about what goes inside of these peoples heads; but I know just enough and maybe even more.

For example: what is considered user-friendly for ME is different than what some others apply user-friendliness to be for THEM. Normal stuff, that happens. But that is it, that is what it is. A planet of over 7 billion people and firefox exists with its specific one user interface. I'm going to want to tweak it.

So that is where this page comes in:

here are some resources for customizing Firefox's user interface and such:

firefoxcss-store

A collection site of Firefox userchrome themes, mostly from FirefoxCSS Reddit

Browser Toolbox

Tool to inspect the UI (user interface)

CustomCSSforFx

A simple general FAQ for customizing firefox

PWAsForFirefox

A tool to install, manage and use Progressive Web Apps (PWAs) in Mozilla Firefox



Don't like Firefox's UI? Here's how to make it better (Firefox CSS)


personally, I think of this to be more of a demonstration rather than a tutorial
