I just made a cohort for the first time.
can't remove users from the cohort in Iceweasel (aka Firefox, works fine in Chromium)
using Iceweasel/41.0.1
JS error:
ReferenceError: event is not defined cohortMembership.js:63:1
cohortMembership.js:62-64 are:
deleteWikiuser: function (wikiuser) { if (site.confirmDanger(event, true)){ $.post(
in Chromium there's a confirmation popup prompt, in Iceweasel no prompt.
I first saw this with an "invalid" user but later reproduced it with a variety of users. deletes were successful (and persistent) with Chromium.
The code is in the analytics/wikimetrics Wikimedia Git repository.
