Speed up Firefox by cleaning out your SQLite databases

A while back, Jason mentioned giving your Firefox performance a boost by limiting the length of time items are saved in history.

At Mozilla Links, they've shared another handy tip from Mozilla developer Jeremy Orem.
His advice: take a vacuum to your SQLite databases. Here's how to do it:

1. Open the Firefox tools menu and click on error console.
2. Paste the following command into the code box as a single line (as pictured):
   Components.classes["@mozilla.org/browser/nav-history-service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");
3. Hit [enter] or click the evaluate button.

After a momentary hang, you'll be able to close the console and return to your main Firefox window to enjoy your leaner, meaner browser!
