Firefox 4 Clear History Solution

I said in a previous post the shortcomings of firefox 4 when it came to clearing the history but through searching forums and the like I have found a solution.

In short, I was talking about how firefox 4 no longer has an entry in the about:config that allows you to automatically delete history after X days. In this new method instead of limiting the history by the dates I now limit it by the number of entries. So in about:config I made a new entry, called places.history.expiration.max_pages entry, and I made the integer be 2500, so now it will delete the older entries if the total number of entries exceeds the number entered in.
