If there is anyone else on DragonFly using Zotero with firefox-esr 52, it seems
as though on May 8th firefox-esr 52 becomes depricated in favor of firefox-esr
60. The new versions of Firefox beginning with 57 break compatibility with a
number of useful plugins.
The Zotero developers have decided to switch to a standalone version that runs
on Linux but doesn't seem to have been ported to *BSD (and likely won't be).
There was some discussion started by a FreeBSD user on the Zotero forums:
My question is has anyone tinkered with the standalone code and found it
buildable/usable on DragonFly? If not what are people planning to use for
citation manager? Zotero is incredibly useful and user friendly.
