To this day, only around 10% of the Firefox extensions that I formerly used function. There are no replacements.
That means for me, the browser is about 90% less functional than it was three years ago. There are so many, many things that I can’t do now and what I can do takes 2-10x as much time.
Why did we have to design everything for fucking morons? Firefox’s motto should be, “Designed by fucking morons for fucking morons.”
