User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

My website https://www.highdefinition.ch does some javascript polling. 
After a fresh restart of firefox, everything works ok. Older versions have been working ok as well. The problem arose recently.


Actual results:

When waiting for a few hours (can be sped up by opening a few tabs of my site instead of one), firefox is getting very sluggish in all tabs but especially in tabs of my site. Since about the last version of firefox, keyboards and mouse events are lost at a 50% which makes firefox completely unusable.


Expected results:

Firefox should not get slow if running for some time. Firefox should not lose input events.
