    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..

    Firefox used to be a great browser, but memory leak issues have never been resolved. The new rapid-release version numbers make me dizzy.

    Thanks for providing a portable version, though. Firefox is still my favourite browser!

    I like Firefox but this version (17) enables Cleartype by default and that's HORRIBLE! !!

    The only way I know to disable Cleartype in Firefox 17 is to disable hardware acceleration in the advanced settings.

    If it wasn't for all this my rating would be 3/5
