At the beginning of every month, my browsing history from the month before the last month suddenly disappears! Anybody have any idea why this might be happening?

At the beginning of every month, my browsing history from the month before the last month suddenly disappears! The previous month's history is still there, but everything before it is just gone! This happens only on my laptop, not my desktop, though I'm running the same version of FF on both (3.6.16). I am running Windows 7 on the laptop now, and XP on the desktop, but I had this problem when I was running XP on both. Someone suggested that it might have something to do with my antivirus software, but I changed that when I went to Windows 7 and the problem remains!

You can look at these prefs on the about:config page to make sure that you keep history.

The method used by Firefox 4 for determining the time that history is retained has changed. The 2 above preferences are apparently no longer functional. The time that history is retained in Firefox 4 is automatically calculated and is determined by an algorithm based each individual system's/computer's configuration/memory. The history is automatically cleaned in the background.

You might want to read these threads at Mozillazine.com:

Mentioned in the above links, is a link to http://blog.bonardo.net/2010/01/20/places-got-async-expiration which apparently was written in January 2010 and appears to be in full force and effect in Firefox 4. In that blog, it says:

  • Also hidden expiration preferences have gone, so browser.history_expire_days, browser.history_expire_days_min, browser.history_expire_sites are now replaced by a single places.history.enabled preference. No more need to read preferences manuals just to make the browser feel faster.
  • What can you tweak? Ideally you don't need to tweak anything, and i suggest you don't touch any pref. Btw, for the sake of information we have two new hidden preferences:
    • places.history.expiration.interval_seconds is number of seconds between each expiration step,
    • while places.history.expiration.max_pages is maximum number of pages that we will retain before expiring.
  • We make our best to have satisfying default values for anyone, current values are built to be pessimistic, we will evaluate how we behave with them, and eventually increase them in future, if we feel that's needed.
