FYI there is ZBX-3878.
Current issue seems like a dupe.

this seems to be ZBX-3878 all over again. can we fix it for good ?

Comment by Oleg Ivanivskyi [ 2014 Apr 29 ]

There is a slight difference, in this case the problem is not related with the slide show.

Comment by richlv [ 2014 Apr 29 ]

true, but in ZBX-3878 various non-slideshow problems were fixed (like some with the time period scrollbar etc)

Unfortunately it would appear that Firefox (tried 24.4.0, 29.0.1) is leaking memory when image elements replaced and there is not anything we can do about it. Chrome handles this without problem. Added comment on issue in Mozilla's Bugzilla.

Need input from Mozilla (see linked issue).

Following comments in Mozilla bugtracker, reloading images don't leak memory anymore when using a nightly build (tried firefox-32.0a1). This means Firefox had a memory leak.
Now just to wait until changes in nightly make it into release versions.
