Part of the problem is Web Extensions can not and will not have the Low Level API and UI Access that XUL had, as such it does not matter how much FF Dev's slow down these extensions will never ever be ported The other problem is many of these extenstions have been in development for years, and have huge complex code bases that can not just simply be ported to Web Extensions, Dev's work on these for free in the spare time so they can not simply quit their day jobs and devote 100% of their times to solve a Problem Mozilla created for their own selfish reasons against the wishes of the User base to appease users that abandoned FF years ago Basically Mozilla is tell the current users of FireFox that we are no longer welcome, to get fucked, and begging Chrome users to come back
