Large images aren't unloaded from memory after tab closed
Hello! I have encountered the following problem: when I open a page with a lot of large images, Firefox obtains a lot of memory and doesn't release it after heavy tab is closed. When I open about:memory tab, it shows several images from closed tab under Explicit/images/content/raster/used. For example, now it uses 1206 MB and I don't know how to release this memory without restarting. Garbage collection and cycle collection on about:memory page don't help.

Empty Cache Button {web link} Cache clearing made easy. One click.
Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.
At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on Cache and Form And Search History.

What about 'Minimize memory usage'?

joyreactor.cc :)) It's a russian entertainment site like yours reddit or 9gag. Problem appears on other sites too, but other sites usually don't have a lot of large pictures, so that serious performance issues appear after a long time.

nope :((
One more notice: the problem doesn't appear on my desktop with Windows 10 installed, only on the laptop with Windows 7. Desktop has firefox version ESR 45.6.0 installed, laptop has the latest 50.1.0. Will try install esr on laptop.
