    Gives a lot of Space for running Virtual machines.

    Also browsers can chew that up fast if you have a lot of tabs, Firefox has managed to do it a few times. At least until I started limiting its RAM to 8GB (best decision ever)

    Limit Firefox to 8GB of RAM .desktop file
    [Desktop Entry]
    Version=1.0
    Name=Firefox RAM limit 8GB
    GenericName=Firefox Ram limit 8GB
    Comment=Limit RAM for Firefox to 8GB;
    Exec=systemd-run --user --scope -p MemoryLimit=8G firefox
    Icon=firefox
    Type=Application
    Terminal=false
    Categories=Utility;Development;
    StartupWMClass=Firefox
    

    (To use it with other apps like Chrome or Electron apps just replace the command at the end, and startup class with the ones from the program you’d like to run. Icon and Name changes are optional but might be desirable so you remember what app it is for).

      Alternatively you can open about:config and limit memory usage there. For example limit in-memory cache.

      EDIT: it seems firefox doesn’t allow to set RAM limits yet, only cache sizes

        Something I didn’t consider when answering earlier is that even if Firefox did have good RAM usage limiting built-in I probably still wouldn’t use it or recommend it, because one of Firefox’s biggest problems is that it leaks. And memory leaks will not be negated by Firefox’s built-in RAM limiter but they will be by systemd’s (or anything else you might be using instead) Firefox would still crash in the event of a leak but it’s still better than it taking gnome or other apps with it, or freezing your system entirely.
