Firefox has gotten a lot more usable in the last few versions, and Chrome-style tab isolation should be here a few versions from now. If they're still screwing up in any major way, it's in the ever-closer approximation of the terrible Chrome UI, but there's an extension [1] which solves that quite handily.
Thanks for the extension link. In my comment though, I didn't mean Chrome interface, I meant the UI of https://history.google.com/. It's now made Inbox-style, but with zero functionality.
I just searched for that and used it for the first time to look to prior searches to use in another comment, and found the interface to be pretty bad. But in writing this comment, I found that it has a "go to date" option at the top and a search box that searches your history. It's actually far better than I thought on first use (but I'm not sure it qualifies as good).
