In order to clarify the method and the feature, it should be noted that this feature does not help if you run the browser and then use it. But it is useful if you run the browser and start browsing, after a long time of opening and closing windows, consumption reaches its maximum limit, at this moment you use the method and the feature to empty the memory of unimportant files through this method. And if you enter Task Manager immediately after that, you will notice that Firefox consumption has decreased.
Certainly, a very distinctive feature. After using it and trying it on a running session for an hour of opening and closing windows, it became clear to me that the method is very useful. But I also advise you not to use many add-ons on the browser, especially if your RAM is relatively low because there are add-ons that consume RAM heavily. So please be careful. I hope the topic is useful and thank you.
