> It broke web experience for me. I write userscripts / extensions for most websites I frequent

Sorry to hear this; but I think it's arguably more important for Mozilla to improve the web experience for a hundred million users who may never "write userscripts / extensions" for any website than to hamstring their development in order to avoid inconvenience to a single user who feels the need to customize every point of their web experience.

So your idea is "nobody cares about you?" :)

Also mandatory signing doesn't improve web experience for anyone. It's a security feature. Security is always inconvenient, almost by definition. So your point is invalid.

I don't mind change, I like new Firefox features, what I dislike is imposition of stupid lockdowns, and pointless control. One valid point, I might concede, is that there are innocent third parties affected if someone clueless confirms installation of some malevolent extension. So restricting it is somewhat justified.

Anyway, it's all still a sham. Anyone can still disable mandatory signing with a simple 10 line script patching omni.ja in any Firefox. So it's still no security against people who can be persuaded to enbale something in about:config, or run firefox with a command switch, or add some file to /etc/firefox/, or run a simple 10 line script "to make firfox compatible with our great extension".
