A curated list and XPI files of Mozilla Firefox browser extensions, addons, themes from addons.mozilla.org, before XUL-based purge blackout.

The removal of the ability to truly have Firefox do what you want was one of the greatest and most senseless (and pointless) eradications of human effort and of useful tools in the history of tech. It also destroyed Firefox and directly led to its irrelevance.

When I recall the things I used to be able to do easily in Firefox that I no longer can achieve in any browser¹, it makes me enraged. And all for no real security or other improvement. Yes, they had to deal with XUL — but instead of creating a better version of that, they took those capabilities away altogether, lied to us that it was for “security” and then laughed at their most devoted users as we said this would doom the browser.

And we were right.
