I think I've used Firefox for about 17 years. Most of the time it's been my main and default browser. During that time, I worked for the Mozilla Foundation for 3 years.
So, given the recent news, it really pains me to even think about switching to Chromium. But, miracles aside, I can't see how Firefox as a browser is going to survive in 2021 with its current market share and resourcing levels 😔
