    The continuation of an excellent browser. In the past, I used Google Chrome, for a number of years. However, in the past couple of years I've been using FF and it has been the best of browsers and I've tried them all.

    Ighome is my home page. It snaps to attention using FF and lags when using Chrome. Hands down, FF is the best browser out there.

    FF has become a MAJOR memory hole.

    After a few minutes, has consumed over a gig of memory and bogs down ridiculously. In their effort to get bigger and better, they got worse and worse.

    Doesn't provide for importing bookmarks from installed version of FF?

    Or have I missed something?

    Guess this would be useful for some, especially for on the go. I keep Firefox from writing to hard drive simply by checking in the Privacy options to clear cache on exit. Nothing gets written to the cache folder that way, just goes to memory until the browser is closed.

    Don't think many pc users know about portable Firefox, or any portable software by asking around. In anycase. This is def. software I can't live without. A version of Firefox that you can install on your flash drive and use on any pc. Also a good way to try the latest version without installing if fully on ur pc. So you can get an idea if you like it or not. Takes a bit of fooling around to inport your desktop firefox settings, but its well worth it..
