This was added so that some add-ons wouldn't show "legacy" on about:addons. With the resigning of everything to external add-ons and the switch to Firefox 57 and legacy add-on only we should be able to remove this.
As of 57, that pref only applies to the UI when "extensions.legacy.enabled" has been flipped to true (in a build that honors it).
In that case, the exceptions pref is used for a bunch of test pilot addons and the default theme.  Test pilot should be okay now but there's still the default theme.  We could:
- replace the pref with a hard-coded exception for the default theme
- remove the pref and let the UI show a bogus "LEGACY" badge next to the default them
- remove LEGACY badges altogether
- do nothing for now

I vote for the last option
Ah good to know the first part. I agree with your vote. So let's leave this in the "stuff to clean out later on" bucket.

Note that this also lets us remove the browser_legacy.js and browser_legacy_pre57.js tests, and their associated resources.

Everything except the pref itself was removed in bug 1563062

The preference has been removed from FF Nightly 73.0a1 (20191213094653). However, it is still listed with a false value on the same build ID on Ubuntu 18.04 LTS and on macOS Catalina 10.15 on FF 73.0a1 Buiild ID:20191212095326.

I'm not seeing that on osx 10.14 and I see no source that has this pref name in m-c. Where do you see this value?

I was looking in about:config for the preference.
Rechecked on Ubuntu 18.04.3 LTS and macOS 10.15 Catalina.
On the latest Firefox version 73.0a1 and build (20191215214948) the extensions.legacy.exceptions is not listed so I marking this as verified fixed.
