2019-01-01 Again on the memory consumption: My main notebook with Crux Linux has 2 GB of memory. It runs a Firefox 8 (yes, I know ...) with 3 windows and in total 1400 open tabs. (That's a lot of tabs, I know, but that's how it works best for me.) The Firefox uses 1.2 GB of memory. My office notebook with Windows 7 has 8 GB or memory. It runs a Firefox 63 with one window and 60 open tabs. It uses about 4 GB of memory. When I had 150 tabs open, recently, I got ``Out of memory: tab crashed'' popups every once in a while. Not at all would it be possible to have ten times (!) as many tabs open ... although the system has four times as much memory. As a sidenote: I had to install a browser plugin [0] just to find out the number of open tabs. [0] http://addons.mozilla.org/de/firefox/addon/count-tabs/ http://marmaro.de/lue/ markus schnalke
