I still use it, but...
they annoyed me greatly when they stopped allowing me to install my own plugins, that I wrote myself, in my own Firefox installation, in the name of increased security.
Yes, I know why they did it (to stop naive people from installing possibly infected plugin files they downloaded from who knows where). Yes, I could still do that in a developer version, and yes I know that somehow, by some arcane process, I could submit my plugins for official approval. But I was never able to figure out the latter, and couldn't be bothered to do the former, and my plugins weren't anything that the general public would have been interested in, just some helpful menu items for some browser-based game I was playing. But it definitely killed my enthusiasm for learning Javascript and how to tinker with web pages.
