Have you tried the dev tools in FF 57? As a FF user with Chrome-as-debugger for 3-4 years, I'm honestly impressed.
FF 57 also has "duplicate tab" with duplicate history.
Thanks for pointing out "duplicate tab". I loved that feature and really missed it on Firefox.
Ctrl-Click on Refresh button acts as duplicate tab in FF for a long time. I am not sure why this option is so hidden but it works.

To be fair you can have a duplicate browser tab in almost any browser by clicking the back or forward button with mouse3.
The (apparently) continuing lack of tab duplication is my major reason not to switch back.
FF 57 has it.
Thanks. Right, that's it, I'm probably on my way back.
It's actually had it for years (probably even always, almost certainly since about 1.5) via middle-clicking the refresh button.
Well, Firefox has existed since before tabs were a thing in browsers, so can't have been always, but yeah, wouldn't surprise me, if this was relatively quickly added after the introduction of tabs.
These kind of hidden features don't require a whole lot of designing and forethought, so it's something that usually only really needs one dev thinking that it'd be nifty to have them implement it.
There are also many features in Chrome that I’ve come to appreciate, such as right clicking a tab and selecting “duplicate”, which opens a copy of the tab and retains the browser history of the original one.
