I think Firefox is an excellent browser. Their problem is simply that they have too much revenue for too many years. They need a fraction of that. If I were the ceo, I would drastically cut back operations. Scale down the org to 10% of its current strength, keep shipping a solid and boring browser, accept donations that directly support development of the browser. No fads, no ai, just a high performance, bug free, standards compliant browser. The users and donations will come. Firefox will survive. One year of google revenue can kar them for 10 years of lean operation!
Revenue is good for the company - and they'll want as much as possible in order to support their obligations to the business plan, but unfortunately layoffs were still part of that plan these past few years. Mozilla's CEO pay:
2018: $2.46 million
2020: $2.97 million
2021: $5.59 million
2022: $6.90 million
2023: $6.26 million
I block requests to Mozilla infrastructure, not by mistake.
