I can show my math if you want (but it’s boring), but I estimate the extensions I can no longer use if I upgrade to new Firefox have saved me something like 3,000-5,000 hours of time over the last decade.
Jesus fuck this is why I hate Mozilla and Firefox developers so much. Not only did they just callously delete all the old, working extensions, erasing millions of person-hours of development, they then reduced the productivity of millions for fake security.
I can’t get over how they just removed all the old extensions in an attempt to memory-hole them — to pretend none of that ever happened. What a bunch of utter dipshits.
