OS: Linux / Mozilla Firefox 61.0
In my daily Firefox profile the about:config pref 'extensions.alwaysUnpack'=
is set to true (has been like forever). Up until and including Firefox 59 =
this worked as expected. Now on Firefox 61 this seems to be removed. At lea=
st that's what I deduce from resetting the pref and seeing that it's no lon=
ger there after a restart. Luckily I keep profile backups, so no vitals bro=
ke when after upgrading to 61 a few extensions (6 out of 28 all-quantum-com=
patible ones to be exact) got (silently) removed from that profile dir.
Trying to check what happened and why ( via regular web-searching, checking=
MDN, official and unofficial forums) didn't turn up any recent info on whe=
ther nor when this pref got removed exactly. I would welcome all pointers o=
n where I could track down this kind of information. Needless to say, if it=
might still be possible to keep extensions unpacked without this pref some=
how, that would be golden info too.
