It's well written and interesting (at least for me) but I wonder: Is this an ad?
It's not specifically declared to be sponsored but somehow its critical paragraphs really don't feel all that critical.
Unrelated but funny: it's stuttering on my Firefox for Android.
It really did gloss over the negative parts and let Mozilla off way too easily. Abandoning extensions is a really huge mistake that I believe will turn away as many users as improved performance will attract or retain. I don't think Mozilla will remain relevant for more than a year or two at this point.
One of positive outcomes from this new firefox strategy is that I will finally learn how to make browser extensions because only one addon I use (uBlock Origin) will work in Fx57 so I have to find alternatives or do it myself.
I like Brave's block-ads-and-tracking-by-default approach.
