Hello, I have trouble with browsing Facebook, sometimes there is a huge memory leak (please check the first uploaded image), and as you can see in the second uploaded image, after I "end task" the Firefox tab that use a lots of memory, the Facebook tab crashed. The third uploaded image is the addons I have installed. Is there a way to solve this? I go to about:memory and click on all there buttons in "Free memory" but that seems to have no effects. Thank you for your time, Tom.
