User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160728203720

Steps to reproduce:

Surfing, watching videos, enabling E10S by force.


Actual results:

After some time (half a day or so) Firefox gets laggy. Videos are sticking (despite having enough buffer to play), Facebook is hanging.
I can only resolve this problem by restarting Firefox. After that, the performance is well again.

OS: Ubuntu 16.04.1
Hardware: Lenovo Thinkpad 420
Plugins: uBlock, ProxTube, Video DownloadHelper, Ubuntu Modifications is disabled


Expected results:

Firefox should be smooth usable.
