Laura Chambers, who stepped into an interim CEO role at Mozilla in February, says the company is reinvesting in Firefox after letting it languish in recent years,
It's sort of amusing to me that Mozilla would let the Firefox browser languish. Is that not the raison d'etre of your entire organization? What are you doing with your time and effort if you are allowing your core product to languish? What would people say if Microsoft said "yeah, we've allowed windows to languish in recent years." What an insane notion.
Note that although species can be described as tree-like, they didn't quite look like modern trees do. Also, much of the world was swamp, and much of the dead plant material sank into these bogs and decayed into peat.
The amount of CO2 trapped during this period caused the atmosphere to be around 35% oxygen. This allowed life with inefficient respiratory systems to grow much bigger in size without suffocating, mainly insects. Think woodlice 6 feet long, spiders the size of dogs, millipedes as big as cars, and dragonflies as big as eagles.
