In the mean time, they've lost one of those power users (likely more, going by some of the discussion in issues for various vim-like plugins) and will, in the future, need to do something to entice me back. This experience has left a bad taste in my mouth and I'm not going to be rushing to go back to a browser that breaks functionality on me without prompt.
They lost me once for terrible, terrible performance. For a year or two until I really needed tree style tabs back. They need to prioritize. Deal with it.
Also, since you're a power user, why don't you use that proposed API already? It seems you don't even need to compile the browser or anything, just enabling a flag and installing the API as an addon.

I am dealing with it. I moved to a different browser.

Simply not true.
We power users are like 1-2% of all FF users. I think it's acceptable to break some things for a while to bring back much more users than that.
