That's the issue - there's no real path to making these legacy plugins work. There are open issues for a keyboard api for FF that has had very little movement over months, so while I'm sure it'll eventually get to a point where I can use FF as I used to, that not being the case now has given me little reason to stay with FF and so back to Chrome I went.
It's too soon to judge, I think. I would be happy using the old FF if the new one didn't have already the things I need. In the mean time I would try to collaborate. Once FF 57 is out of beta officially, there will eventually be enough people with itches to scratch. It was in my plans to implement Tree Style Tabs properly if no alternative appeared before end of the year.
It's not too soon to judge - plugins I used no longer work unless I turn off auto-update or move to the LTS version. The team knew these were breaking changes for months or years, but the APIs to un-break things don't exist and aren't prioritized. It's discouraging to collaboration when you look at 2+ year old issues (https://bugzilla.mozilla.org/show_bug.cgi?id=1215061) that still haven't been properly addressed.
You make it sound like there's no movement, but I see enough movement to have both short-term alternatives, and medium term fixes. Read comment 46 and the next ones. They were super busy with what they can actually release with FF 57. Until today the issue wasn't really pressing. In a few days we'll see if they're serious about that issue.
You don't break something and then prioritize fixing it. That's backwards. If they knew it was going to break the proper thing to do it prioritize the fixes before it effects end users, not after. If I were to push up a breaking change this morning and just wait for bug reports, I'd be looking for a new job by this afternoon.
I would agree with you normally. But in this case there's a much bigger "bug" they must handle: The vast majority of users have migrated to Chrome or some other browser that don't respect their privacy.
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.
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.
