How to reproduce:
use Firefox (using 35 here), enable hovercards and hover over a link.
Expected behavior: pop shows as long as you are on the link and disappears after some milliseconds.
Actual behavior: hovercard get stuck and doesn't disappear. New hovercards don't show.

I can reproduce the problem in Firefox 35 on F21 only with the "Adblock Plus" addon enabled in Firefox. Can someone confirm?
this must be caused by a recent (<2 weeks?) change in FF, Adblock and/or MediaWiki (Popups, ..).
I suspect this is caused by a blocked request to https://bits.wikimedia.org/event.gif? [...] which blockage isn't handled nice in event tracking and/or popups code.
On leaving the hovercard a request is created (and appears as blocked in Adblock Plus), simultaneously Web Console gets a red x entry with message ":" only and location (via debug=true) at ext.eventLogging.core.js:222 (1.25wmf14) in the EventLogging-Extension.
closing as T86680 got fixed. Change has been deployed. I haven't seen that issue afterwards for me.
