Re: 30 per cent faster
My tests of FF 56 and FF 57 using Mozilla Speedometer show a 16% speed increase for 57.
If it's not just made up, the 30% figure probably includes improvements made prior to the release of FF 57 (and it is definitely true that 56 and 55 were both noticeably quicker than the version prior), which also helped boost the performance of FF 56 with the full addon API. It demonstrates that significant improvement in speed was possible without cutting off the "legacy" addons, and there are probably some additional gains to be found.
I'm all for optimization, but I am not in favor of cutting out important features to get there. If there were alternate APIs that allowed the kind of customization that used to be possible with the old addons, or if the options those addons I use were built into the base FF product, that would be different. As it stands, the legacy addons are indispensable to me. Greater speed isn't... it's nice to have, but not necessary.
