Why does Firefox leak memory after. I do the same operations in Firefox and Safari, Firefox in some cases uses over 500 MB of RAM, Safari uses about 50 MB

After opening and closing 5 windows in Firefox and Safari, at rest Firefox still claimed (approx.) 500MB of real memory, Safari return all memory and claimed only (approx.) 50MB at rest (all windows closed). My laptop starts over heating when browsing just simple information pages in Firefox. This still happens after updating to the latest browser.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
