the web browser isn't a sentient entity; the web browser is developed by people who are part of an organisation with an ethos.

I think the question was:

List the steps to be taken by the people at Mozilla to achieve this. Then think if those can reasonably be accomplished.

y’all need to stand up against racism and discrimination

I concur, I think they should push towards a more positive internet. Though I think they are a bit wary of doing it ever since the toxic backlash to this blog post

We need more than deplatforming – The Mozilla Blog (Archived)

There is no question that social media played a role in the siege and take-over of the US Capitol on January 6. Since then there has been significant focus on ...

The Mozilla Blog (Archived) (blog.mozilla.org)

Both currently sucks.

The fact that they are now selling our data seems like both a browser problem and a leadership problem. If the browser were fine, we wouldn't be seeing a moderate exodus to choices like Librewolf and Zen.

For those holding out for a hero: https://ladybird.org/

Ladybird is a brand-new browser & web engine. Driven by a web standards first approach, Ladybird aims to render the modern web with good performance, stability and security.

I dunno, Firefox of 3.0 times was the shit. It itself was the browser that should be, more welcoming to customization than Windows of the time was to porn winlockers. They also had XULRunner for alternative ideas. Gecko was the FOSS browser engine that various alternative "nice" MacOS and Linux browsers used.

Though between 2004 and 2008 only four years passed. Less than between Windows 2000 and Vista (let's ignore XP as a more glossy consumer version of 2000).

which is exactly why they need a strong positive leadership that doesn't bend the knee to bigots.

the ladybird devs have a history of major transphobia though

I'm not looking for a hero, I'm looking for stability.

All firefox really needed to be once google took over everything, was to be a viable alternative and find a way to metabolize all this cash in a way that doesn't damage google's own cash machine or threaten it's actual dominance.

For google the pitance they give firefox is a very cheap insurance policy against against anti-trust legislation.
Just like Intel with AMD, this shows how toothless the liberal anti-trust legislation are, even if they were really being enforced, they cannot handle a token 2nd player. It cannot handle controlled opposition if it's credible and believable. So an actual thriving ecosystem doesn't need to exist, we just get duopolies instead of monopolies but in practices we get ducked up the cloaca just the same.

some context and/or link would help for everyone who just learned about this project and knows nothing about the devs

I think this may be the issue to which you are referring:

Ladybird and the Controversy over Inclusivity - Review

What people were upset about, why it blew up, and why some people are still leery of the project to this day.

Kelson Reviews Stuff (hyperborea.org)

While this is troubling to read about, this narrative’s lack of evidence or references keep me from accepting it at face value. Old mastodon chatter (and perhaps deleted posts or scuttled instances) may be difficult to retrieve, but GitHub discussions shouldn’t be hard to find.

So I’m withholding judgement for the moment.

UPDATE: Commenter lime!@feddit.nu wrote this terrific comment that provides confirmation of the above narrative, corrective action that the LadyBird engineering team has taken taken, plus some vitally important context of the entire kerfuffle. A+ work.

with a project named ladybird you'd think otherwise.

There was a pull request to change "he" to "they" somewhere in the code and the dev refused, saying people should leave "their politics" out of it. I wouldn't say it's transphobic specifically - it may also be misogynistic. Either way, it doesn't look good.

I'll just copy a comment I made a while back. It was about the usage of "he" instead of gender neutral pronouns in the documentation:

So I looked further into this, and while I found awesomekling's comment to be a cause of concern, I'm hoping it's a cultural misunderstanding due to his Swedish background.

That comment is from 3 years ago, and since then there was a commit merged, that had the sole purpose of fixing these pronouns.

For clarity, Mozilla isn't one thing. There's Mozilla Corporation (profit) and the Mozilla Foundation (nonprofit). Firefox is a product of Mozilla Corporation. And yes, the need to make a profit is a bug not a feature.

You don't consider it rather exclusionary to imply that only men use computers?

That's a weird way of saying firefox is not fine.

I’m hoping it’s a cultural misunderstanding due to his Swedish background.

Jag pratar inte Svenska but I know enough that it has gendered pronouns just like English. Actually, it's better than English in that it preserved the neuter singular pronoun (which used to be "thou" in English) so there's even less excuse in terms of linguistic background.
