Firefox 3.0.1 Fixes 'Carpet Bombing' Issue

An anonymous reader writes "Firefox 3.0.1 was released today. It fixes 3 security vulnerabilities, including a critical issue reported by Billy Rios, Ben Turner, and Dan Veditz. The issue could be combined with an issue in Apple's Safari browser to read data from the user's disk or to execute arbitrary code. This issue was previously discussed on Slashdot. The release also fixes a remote code execution bug involving the CSS reference counter, reported by the Zero-Day Initiative (previously discussed on Slashdot here), as well as a Mac-only potential code execution bug involving GIF image rendering, reported by Drew Yao of Apple Product Security."

      Hmm, a Google search reveals that while the "awesome bar" is still the default, you can disable it by following the directions below (but, maybe you already knew this):

      1. Type about:config into the location bar and change the value browser.urlbar.matchOnlyTyped to true. After this, you need to restart Firefox. All this does is make it so that Firefox only searches the URLs you have typed and not the titles of pages.

      2. Install the Old Location Bar extension. This changes the location bar so that it looks like how it looked in Firefox 2. As of me writing this post, it is an experimental addon so you will need to register to the Firefox addon service to install it.

      Yeah, well, the FF2 bar wasn't all that hot either. The only thing more annoying than waiting for the list of sites to never come up because you started typing while another tab was still loading, is having the list of sites popup while you're typing and since you had the mouse in the wrong location when you hit enter you went to some completely different place than you had expected.

      I don't care whether it's awesome or not, give me an option to make it not appear unless I press down or alt-down or tab or something that indicates that I want it to appear.

      When you run an application from Windows Explorer, it is normally run with its current directory set to the directory that the executable is located in. The vulnerability exposed by the "carpet bombing" attack involved attacking Internet Explorer, because Internet Explorer runs with its current directory set to the desktop... not the directory containing the IE executable.

    OK, if you saw the following I may have an answer for you. If you installed FF3 and around a day or two later mysteriously it seemed to put up the hourglass cursor with the disk thrashing a lot, then you got bitten by the urlclassifier db (anti-phishing sqlite database) being downloaded. After a day or so things go back to normal. (It would look more like a temporary freeze of the program rather than a crash to the desktop).

    For anyone on a slow connection or with an old machine (like me) that was almost a showstopper. Thankfully, *seems* to be fixed now.Haven't seen any real crashes to the desktop even with the betas...

  27. A brief future history of the awesome bar by violet16 · · Score: 2, Insightful

    Let me save you some time and map out your journey to acceptance of the awesome bar.

    First you hate it, because it's new and different to what you expect. You are trained to use it as an address bar and nothing else, so it acting like a search bar is confusing and suboptimal to you.

    At this point many people decide to trial the new bar, but you are the kind of person who tends to think he (forgive me, but he) knows what's good and what's not, and even quite enjoy the idea of customizing your Firefox. So you look for a way to preserve your old behavior. There are enough people like you to make worthwhile a mass solution: a config option and an extension.

    You and your anti-awesome fellows make use of these. You occasionally grumble that the awesome bar shouldn't be default at all, but you are basically satisfied so the rest of the world hears from you less and less.

    As time passes, you occasionally find yourself using other people's computers that have Firefox in a default state. This annoys you at first and if you are spending any serious time on them, you disable the awesome bar. But sometimes you're only using them briefly, so it's not worth modifying. Then, all of a sudden, you find the awesome bar useful. It's a surprise, like a door opening: you suddenly see that if you alter your behavior a little, the awesome bar could be quite useful.

    From this point you never disable the awesome bar again, although you leave it disabled on your main desktop, as a matter of principle.

    A new version of Firefox is released. The "Disable Firefox Awesome Bar" extension hasn't yet been updated to work on it. But by now you don't really mind. You now prefer the awesome bar. When you have to use Internet Explorer, or Firefox 2, the lack of an awesome bar bugs you. It seems so inflexible, so archaic.

    A while later, the author of the awesome-disabling extension stops updating it. People forget that anybody ever didn't like the awesome bar. But this new Firefox feature, the predictive URL form mapping--oh man, that's just so horrible, why is it on by default?
