Mozilla Sued for Discrimination by Former CEO-To-Be
The story this lawsuit tells is a Game of Thrones style power struggle.

The Lunduke Journal has obtained the legal documents regarding a new lawsuit which has been filed against Mozilla, makers of Firefox, by a former C-Level executive.

And parts of it read like a Game of Thrones style power struggle within the browser maker.

  • The Mozilla Chief Product Officer was being groomed to take over as the new CEO.
  • That CEO-to-be took some medical leave to treat cancer.
  • In the days (literally) before the CEO-to-be returns from medical leave... the then-serving CEO of Mozilla, Mitchell Baker was fired -- by the Mozilla Board -- abruptly.  No warning.
  • The Mozilla Board of Directors then installed one of their own Board Members, Laura Chambers, as the new CEO.
  • All before that "CEO-to-be" could return to work, from his medical leave, and take over the CEO position.

There is a lot here -- including a tale of discrimination and abuse inside the Mozilla Corporation.

Below are screenshots of large portions of this lawsuit -- the items of particular interest to tell this story -- with each screenshot followed by a brief description and some additional details.  (If you're short on time, just read the descriptions between each screenshot... that will give you a high level overview of this story.)

 

Lawsuit: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

The lawsuit was filed by Steve Teixeria (the former Chief Product Officer of Mozilla), against Mozilla Corporation, in King County, Washington (Seattle), on June 12th, 2024.

Teixeira, the new Chief Product Officer (CPO) of Mozilla was brought on board in 2022 and was being groomed to become the new CEO (to replace Mitchell Baker).  This appeared to be the plan from Baker and at least one Mozilla Board Member.

As CPO, Teixeira led roughly 75% of the employees of Mozilla, and oversaw the "entire commercial product portfolio".

Firefox is reaffirmed to be roughly 90% of Mozilla's revenue.

As CPO, Teixeira, was given high performance reviews.

Mozilla opened an entire office branch -- in Seattle, WA -- to accommodate Teixeira.  Which would make sense if the plan was to make Teixeira the new CEO.

Through September of 2023, the plan remained to transition Teixeira to become the CEO of Mozilla.

Teixeira was diagnosed with cancer (ocular melanoma) in October of 2023.  He then took leave (under the Family Medical Leave Act) until February of 2024.  Mitchell Baker remained CEO during that time... until the days before Teixeira returned to work.

Mozilla publicly announced their new CEO, Laura Chambers, on February 8th, 2024.

According to this legal filing, that decision was made (by the Mozilla Board), internally, roughly a week prior.  This would be "shortly before Mr. Teixeira" returned from leave on February 1st, 2024.

This legal filing appears to say that Mitchell Baker was fired, by the Mozilla Board of Directors -- from her role as the CEO of Mozilla due to her "declining performance".

The timing here is interesting.

According to the legal filing, the firing of Mitchell Baker as Mozilla CEO was "so abrupt that they did not conduct a search for a successor".

Meaning: They were in a hurry.  For whatever reason, the Mozilla Board needed to act right then.

And the Mozilla Board -- which included Laura Chambers -- voted to install Laura Chambers as the new CEO.

All of this happened the very moment the person who was being groomed to take over as CEO, Teixeira, returned from his medical leave -- and was set to resume overseeing roughly 75% of Mozilla.

Was this the motivation for moving so quickly to install a new CEO?  To do so prior to Teixeira returning and taking over?

The first day back as CPO, Teixeira was instructed to lay off 50 (already selected) employees.  He had questions about who had been selected to be laid off.

Teixeira's employees were "explicitly forbidden", by the "Chief People Officer" of Mozilla (Dani Chehak), from briefing and assisting Teixeira as he returned from leave.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira expressed concerns, with Human Resources at Mozilla, that these layoffs would "disproportionately impact" "female leaders" and "persons of color".

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira was threatened, by the Chief People Officer (Chehak) to be forcibly placed "back on medical leave" if he "did not execute the layoffs as instructed".

Do what we say, fire these exact people, and don't talk to anyone about it.  Or get out.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

The new CEO, Laura Chambers, and the Chief People Officer, Chehak, insisted that Teixeira not only announce the layoffs... but falsely take responsibility for the layoff decision-making.

According to this document, Laura Chambers was throwing the person that was being groomed to be the CEO under the bus.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira was "permitted only to speak with the CEO and her direct reports".  His staff -- roughly 75% of Mozilla - was delayed being moved back under his leadership.

There was an "outside audit" done of Mozilla's performance in "providing a diverse, equitable, and inclusive workplace culture" by Tiangay Kemokai Law, P.C..

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

According to that outside report, Mozilla's leadership provides an "inadequate response to the needs of a diverse culture" and is "incongruent with [Mozilla's] stated values and goals."

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira's former direct reports expressed, to him, "deep concerns" about leadership in his absence.  Specifically regarding "abrupt changes to strategy" and "inappropriate or abusive interactions" from the Senior VP of Strategy Operations (Suba Vasudevan) and the Chief Marketing Officer (Lindsey O'Brien).

This included complaints made to Human Resources regarding the Chief Marketing Officer.

What those complaints were, we do not know.

The new CEO, Laura Chambers, hired a consultant to assume Teixeira's core responsibilities after Teixeira returned from medical leave.

Teixeira then received, from the newly installed CEO, his first negative performance review.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira -- once groomed to be the new CEO -- now was being forced to move into a new role. Which he did not want or ask for.

At this time he was able to work full time and did not request time off for medical care.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira's family believed that Mozilla was gathering his publicly available medical information, to be used against him in his employment.  His family then begins to remove public information regarding his medical status.

Teixeira disclosed to the new CEO (Laura Chambers) that liver cancer had been detected.

That information was then shared -- according to other statements within the lawsuit, by Laura Chambers -- with all of her direct reports.  

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Mozilla then makes it clear they wished to demote Teixeira (from a C-level executive down to a Vice President role).

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Teixeira declined the demotion (which would come with a 40% pay cut and the job would end, entirely, at the end of the year).

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Mozilla's CEO, Laura Chambers, then disclosed significant, private details of Teixeira's medical conditions to other Mozilla employees.  Without Teixeira's consent.

Chambers also told other Mozilla employees that Teixeira would be demoted (the demotion that he had just rejected).

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

A key note here: Teixeira had "not requested additional flexibility related to his disability."

On April 25th, Teixeira made a complaint, in writing, that he had been discriminated against because of his cancer.  Two days later, on April 27th, the CEO (Laura Chambers), "retaliated against Mr. Teixeira" by telling him, in a nutshell, to "take the demotion or you're fired."

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Mozilla, over the next couple days, began panicking -- instructing Teixeira not to discuss anything related to his employment with Mozilla... with anyone.  Even going so far as to draft up a new "non-disparagement and non-disclosure" document with new restrictions.

By the next week Teixeir was placed on "administrative leave".  His direct reports all reassigned to other executives.  His chief of staff fired.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Mozilla refused to provide a reason for these actions.

Mozilla then cut off Teixeira's access to all Mozilla systems (including email and messaging) -- and instructed Mozilla employees to "not communicate with Mr. Teixeira."

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

A few weeks later an "investigation" was launched into Teixeira's discrimination allegations.  However Teixeira was never contacted to participate in the investigation.  Which is strange, to say the least.

Normally an "investigation" involves all parties involved.

It would be very interesting to see the full results of that "investigation".

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Mozilla continued to falsely state that Teixeira was on "medical leave", and provided Teixeira's medical details to other employees without his consent.

Which, if true, means Mozilla is likely going to be anxious to settle this lawsuit out of court.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

This resulted in multiple Mozilla employees being led to believe that Teixeira "would pass away imminently" -- which, obviously, would be pretty distressing for both the remaining Mozilla employees and Teixeira and his family.

 

Source: Steve Teixeira vs Mozilla Corporation (et al), June 12th, 2024

 

Based on the details of this lawsuit -- should the details all prove accurate -- it certainly doesn't paint Mozilla in a good light.

  • A CEO ousted -- abruptly -- in the moments before a "New CEO-To-Be" returned to work and could take over?
  • The Mozilla Board acting with lightning speed to install one of their own into the CEO position?
  • Silencing.  Scapegoating.  Discrimination.  Abuse.

Raises many, many questions about what has been going on within Mozilla... and how specific individuals rose to power within the organization.

This document, of course, is merely one side of the story.

Should this case move to trial, we would hear Mozilla's side of the story.  That, however, seems unlikely... as these sorts of cases -- especially when they appear this strong -- tend to be settled pre-trial.

The Lunduke Journal has reached out to to both Mozilla and Teixeira for comment.  As this is an ongoing lawsuit -- and Mozilla has a strong track record of silence and secrecy -- no response is expected.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

The 100x Architect: Why the "Vibe Coding" Argument is a Dangerous Coping Mechanism

I hear it constantly from my fellow nerds: “I’m not worried. Non-coders ‘vibe coding’ AI slop will never be a threat to my job.”

You’re 100% right. Vibe-coded slop isn't the threat. The threat is top-talent developers who also master GenAI tools.

While the skeptics are busy mocking juniors for generating buggy Todo apps, they are missing the real shift: the veterans with 40 years of patterns in their heads who are using GenAI as a 10x multiplier.

The math is simple: 10x1 is 10. 10x10 is 100.

If you are a talented dev (a 10), and you refuse to use the multiplier, you aren't "staying pure"—you’re just being out-scaled by the people who have your skills AND scale themselves with GenAI.

A Field Report from the 100x Front:

In two recent projects—one for a paying client and one for a friend—I built in a few hours by myself what would have traditionally taken a small team a couple of weeks...

Lunduke Journal Week In Review - Jan 16th, 2025

Whew! It’s been another wild week for Tech News!

Here’s a crazy stat for ya:

We are currently 16 days into 2026, and The Lunduke Journal has already recorded 19 shows (17 of which have been published on every platform, and 2 others to be published this weekend everywhere… but are already available via the MP4 download page). And that’s with taking New Year’s Day off (and getting the flu this week).

It’s a heck of a lot of Tech News, to be sure.

Lunduke’s Top Stories for the Week

If you only have time to watch a few of shows, I recommend these 3 as being the most interesting (or important… or just… strange) from the last week:

In other words: A pretty gosh-darned crazy week for Linux.

(Those links are to Lunduke.Substack.com, but you can watch all of those shows on any other platform. As always.)

Other Tidbits of Awesomeness

A few other notes on this, most excellent, Friday!

And, with that, I leave you with a screenshot of the MP4 listing of the shows so far in 2026. Bonkers.

Lunduke's Lifetime Subscriber Wall 3 is almost full!

Holy moly.

This afternoon I sat down to update the 3rd Lunduke Journal Lifetime Subscriber wall — adding in all of you who sent in requests over the last week or so.

And, boy howdy, were there a lot of you! So many, in fact, that the 3rd Lifetime Wall only has room for around 6 or 7 more names (depending on the name lengths)! That’s crazy!

If you want to make it onto “The Lunduke Journal Lifetime Subscriber” Wall number 3… send me an email (bryan at lunduke.com) with the way you would like your name to be displayed.

Or, if you’re not already a Lifetime Subscriber, remedy that for $89. (Which, you know, is a pretty gosh darned good value.) … Then send me that email requesting to be added to the wall.

Once Wall 3 is full, we’ll start in on Wall number 4 (that’s nuts). At the current rate, I expect Wall 4 to debut this week.

And, as always, thank you for your support. Whatever kind of subscription you have, it is deeply appreciated. Monthly, Yearly, or Lifetime. All are amazing. You make The Lunduke Journal possible.

You rule.

Lunduke Out Sick Tomorrow

I’ve got the flu (or something else yucky) and need to take the day off tomorrow.

But I don’t really have a normal “boss” to email. Heck, all of you are sort of like my collective boss.

So I’m emailing you:

Boss, *cough cough* Lunduke is out sick tomorrow.

Which means no new shows on Wednesday. Hoping to rest up and be back with new shows on Thursday.

If you’ve missed any shows over the last few weeks, now’s a good chance to catch up.

And feel free to grab one of those fancy-shmancy $89 Lifetime Subscriptions while you’re at it. That won’t make my flu go away any faster… but it definitely won’t hurt.

Unrelated note: Buying stock in Nyquil might not be a bad idea. I think I’m about to increase their profits.
