You may want to check and try following preference.

  - browser.tabs.unloadOnLowMemory
  - browser.tabs.min_inactive_duration_before_unload
  - browser.low_commit_space_threshold_percent
  - browser.low_commit_space_threshold_mb

I just realize that `browser.tabs.unloadOnLowMemory` is `false` by default. Turning it on may help.
`browser.tabs.unloadOnLowMemory` is how long before a tab being able to be unloaded.
`browser.low_commit_space_threshold_percent` is the percentage of memory being used to kick unloading.
`browser.low_commit_space_threshold_mb` is the megabytes of memory left to kick unloading.
