Are you like me and have made several changes to your Firefox registry file or "About:Config" file? Well just like any other changes that take time to do you want to back them up so that you will not have to go thru the trouble of redoing all that work. It is pretty easy and painless thing to do all you need to do is know where to go to get to the file that you need which is call "prefs.js" and for your Firefox installation on your desktop computer it can be reached by clicking on your start button, choosing Run and typing the following: %appdata%\mozilla\firefox\profiles If you do not have several Firefox profiles you will see a file names with 8 random characters followed by .default That is the file you want to open where you will see something similar to what's in the picture to the left. The file that you are looking for is "prefs.js" once you locate it you will need to save a copy of it to a safe place. But how do you do this for your portable version of Firefox you ask? Well you might not have asked but that was the first thing I thought of when I learned about this little tip was that my desktop installation of Firefox does not get used nearly as much as the one on my thumbdrive. So here is where you would locate that same "prefs.js" file for your Firefox on a stick. Since I have installed the Beta version of Firefox 3 beta version 4 I would look here for the file. PortableApps\FirefoxPortableTest4\Data\profile The reason I mention this is that for some reason when you install the portable version on your USB thumbdrive it has the "prefs.js" file on there twice and only one of them has the information that you want to save.
