A side effect of using the Vimperator extension for many years was that it provided a stable interface unaffected by upstream UI tweaks, while still benefiting from other feature and security updates. I couldn't imagine switching away from Firefox for any reason, but when Vimperator was no longer supported, I realized I didn't like what remained and evaluated alternatives. Eventually, I stopped installing Firefox on my machines because I no longer open it.
