    Default How to speed up Firefox 3 dramatically.


    I've been suffering with a very slow Firefox 3.0.1 lately, and just figured
    out how to cure this.

    Thought the rest of you might want to try it and see if it helps your
    experiences with FF3.

    There are several bug reports concerning heavy drive thrashing and slow
    operation. These all boil down to the way FF3 is handling some data.

    To help people identify Phishing sites, forgeries (phorgeries?) and general
    ickiness, FF3 contacts Google.com for EVERY http request. EVERY REQUEST.

    And then it saves the results into 'urlclassifier3.sqlite' in your profile.

    This file grew to more than 50MB, at which point I read that you could
    'vacuum' it using 'sqlite3' to drop the unused database entries. I did this,
    it shrank to 33MB, a savings of 17MB... but the thrashing continued.

    If you will disable the Google checks, then exit FF3 and delete the
    'urlclassifier3.sqlite' file from your profile, your FF3 experience will be
    much nicer, albeit at the expense of some assistance in Phish Site Phinding.

    Turn off these two options: (under preferences)

    Security -> "Tell me if the site I'm visiting is a suspected Attack site"
    Security -> "Tell me if the site I'm visiting is a suspected forgery"

    Close the preferences window, exit Firefox, then delete the
    'urlclassifier3.sqlite' file:

    rm .mozilla/firefox/*/urlclassifier3.sqlite

    The file WILL be recreated upon the next start of Firefox3, but it's only
    32KB in size, and isn't expected to grow since the two "Tell me" options are
    off.

    It's made a world of difference in the browsing experience for me.

    Hopefully this helps others.

    How dangerous are phishing attacks really? I mean, assuming I don't click on any links to paypal sent to my by my new rich friends in nigeria, isn't the danger pretty low?

    If you know what you're doing, and is able to recognize a phishing scam if one appears on your doorstep, then do it.

    For people new to the 'Net (and those who are not so sure what a phishing scam is) it is recommended to keep the default settings enabled.

    YMMV. Be careful, it's a wild, wild web out there...

    {Smile} If you're worried about 56Meg of space in THIS day and age.. OMG!

    That works out to just about 0.00219% of my current total storage space.
    Just over two one-thousandths of 1 percent of storage.

    Even if you had a nice 250GB drive, it's 0.0219%, that's just over 2
    one-hundredths of 1 percent. Rather minuscule.

    Granted, I STARTED out on a 4K machine. Not Gig. Not Meg. KILO.

    Want me to start in on the 'uphill both ways', 'hole in my shoe', '5 miles to
    school' stories now?

    I learned how to program when memory was Thou$ands of dollars per K... and
    have tried to apply that experience to everything I write now. Generally
    makes programs faster too. {Grin}

    Oh well.

    i test firefox nightlies. for example today's build is:
    Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1a2pre) Gecko/20080821020715 Minefield/3.1a2pre - Build ID: 20080821020715

    this seemed to work well for me too.

    i have a question regarding this though. does anyone know if this is a natural occurence? if it isn't expected to happen over time, then perhaps someone should file a bug about it, with a title something along the line of:
    Suspected Attack Site/Suspected Forgery checks slows Firefox down.

    Its not a bug as such, just a security feature that some may prefer to disable. (Similar in nature to beagle indexing that can cause annoying resource issues).
