Stop Mozilla Firefox killing your SSD

Many people notice that latest versions of Mozilla Firefox save a session backup to disk every 15 seconds. At such rates Mozilla is able to easily write up to 15 Gigabytes of data to your SSD per day. Of course such enormous amount of written data can significantly reduce the life of any SSD. Here is how to change the current session auto saving time period and stop Firefox killing your SSD.

  5. Type browser.sessionstore.interval  in the search field.
  6. Set browser.sessionstore.interval to 600000 (10 minutes) or even bigger to increase the time span for Firefox to save the current browsing session to disk: browser-sessionstore-interval-change
  7. Restart Mozilla Firefox browser.
    From now on your Firefox browser will save the browsing session every 10 minutes but not every 15 seconds. Good luck!
