Hello, I am having trouble changing my browser history settings. When I go into about:config, I see browser.history_expire_days.mirror. I tried to add browser.history_expire_days as an integer, but it wont save. What can I do to the settings to make sure that the history will be deleted after a certain number of days? Thank you!

The browser.history_expire_days and browser.history_expire_days_min prefs have been removed in Firefox 4+ versions and replaced with a single places.history.enabled pref to remember history or disable the history. If you still have them then you can right-click them on the about:config and reset them to the default values and they will be removed on the next start from the about:config page.

You can look at this extension:

.......... Firefox 4+ versions do not have a time limit for the history.
Firefox determines automatically how many pages can be kept without affecting the performance.
You can see the current value via the read-only pref places.history.expiration.transient_max_pages on the about:config page.
