Must Have SEO Firefox Extensions

Saturday, October 13th, 2007
  1. Firebug – With this helpful little add-on, you
    can tweak and monitor CSS, inspect and edit HTML, debug, visualize CSS
    metrics, monitor your network and also make changes in JavaScript live
    in any web page
  2. Google Global Firefox Extension – As results for Google differ from one country to another, results become limited. The end to this problem is Google Global.
    Global is an unobtrusive Firefox extension that allows you to see
    what the Google search results that you are viewing, look like from
    different geographical locations. This is very useful if you want to
    compare organic search results in different countries or if you want to
    see how your AdWords PPC campaigns appear in different regions. With
    Google Global, you can change depending on your personal browsing
    habits. You can open the search results in a new tab, useful for
    comparing results, you can add as many countries to your Google Global
    search options and you can also depersonalize the search results shown
    by Google Global
  3. Google Webmaster Tools External links ++ – With
    Google Webmaster Tools External links ++ you can check the PR of the
    pages linking to you and the anchor text used on the link. This
    Greasemonkey script determines PR for the link through an XML HTTP
    request and adding it in front of the link. You need to have Google Webmaster Central Account and the site added and verified in it. If the link is found, and it’s normal, the PageRank and anchor text is displayed in black, with the anchor text within quotes.

    • If the link has rel=”nofollow” on it, the info is made orange and striked through.
    • If the link is not found the info is made red, and the text “Link not found” is added.
    • If the link is an image link, the text “img, alt:” with the alt text is added. Since v1.1
    • If a single frame is encountered, the script opens it and tries that for the link, matching Google’s behavior. Since v1.1
    • URL’s without www are now properly recognized as well.
  4. LinkChecker – With LinkChecker, you can check
    webpage links at a glance with simple color coding. Ditch those massive
    listings of bad links that provide no context and add LinkChecker to
    your arsenal of web development tools today. The best thing about this
    extension is that the creator, Kevin Freitas is constantly developing
    it and some of the expected upcoming features are:

    • Sidebar with broken link summary list anchored to bad links
    • Link duplication checking/count
    • Options dialog to set timeout, color, skip criteria, right-click menu visibility, and other settings
    • More detailed or SVG progress pie chart
    • Easy bookmark link checking (currently achieved by finding your
      bookmarks.html file on your computer, loading it in Firefox, then
      running LinkChecker — not exactly ideal, is it?)
    • Abilty to remove or “turn off” LinkChecker colors after check is complete
    • Option time delay each link checked so script not seen as robot
  5. RankQuest SEO Toolbar – RankQuest SEO(Search
    Engine Optimization) Toolbar provides you quick access to more than 30
    intuitive SEO tools. Alexa Rank and Page Rank provided by Alexa and
    Google respectively ensures the popularity of the site. Once you
    download and install the SEO Toolbar you are only one or two clicks
    away from carrying out most of your day to day SEO operations.
    available in Japanese, Italian, Polish, Spanish, Swedish, German,
    Dutch, French and Chinese languages.
  6. SearchStatus – Display the Google PageRank,
    Alexa rank and Compete ranking anywhere in your browser, along with
    fast keyword density analyser, keyword/nofollow highlighting,
    backward/related links, Alexa info and other SEO tools. In simple
    words, you can check how any website, no matter where in the world, is
    performing. With SearchStatus, for every site you visit, you can view

    • Google PageRank
    • Google Category
    • Alexa popularity ranking
    • ranking
    • Alexa incoming links
    • Alexa related links
    • Backward links from Google, Yahoo! and MSN
  7. SEOpen – Provides some basic tools to help with
    search engine optimization. Including google backlinks, yahoo
    backlinks, PageRank check, http header viewer, and more. All features
    are available by right-clicking on an open area of a web page, or by
    using the included toolbar.
    Highlights of SEOpen 0.8 are:

    • Yahoo Backlinks
    • Pages in Yahoo Index
    • Google Backlinks
    • Google Cache
    • Pages in Google index
    • Google Translate to English

    HTTP server (eg. Apache, IIS, etc.) runs on the visited sites. When a
    tab is selected, the corresponding server name is shown on the
    right-hand side of the browser’s status bar
  9. Web Developer extension – The Web Developer extension
    adds a menu and a toolbar to the browser with various web developer
    tools. It is designed for Firefox, Flock, Mozilla and Seamonkey, and
    will run on any platform that these browsers support including Windows,
    Mac OS X and Linux.
  10. X-Ray – With X-Ray, without viewing the
    sourcecode, you can see the tags on a page. One installed the X-Ray
    command is available by right-clicking as well as in the Tools menu.
    When applied to a page it can help you see how the document was
    constructed without having to go back and forth between the sourcecode
    and the page in your browser. Is that list made of li, dd or p
    elements? Is that an h3 tag or just some bolded text? X-Ray shows you
    what’s beneath the surface of the page.

How to create Firefox extensions

Thursday, October 4th, 2007

Extensions are small add-ons that add new functionality to Firefox, from a simple toolbar button to a completely new feature. They allow
you to customize Firefox to fit your own needs and preferences, while letting us keep Firefox itself light and lean.

Useful Firefox Security Extensions

Thursday, August 2nd, 2007

Useful Firefox plugin list:

  • Add n’ Edit Cookies This might be more of a web developer tool, but being able to view in detail the cookies that various sites set on your visits can be an eye-opening experience. This extension not only shows you all the details, but lets you modify them too. You’ll be surprised at how many web apps do foolish things like saving your password in the cookie.
  • Dr. Web Anti-Virus Link Checker
    This is an interesting idea — scanning files for viruses before
    you download them. Basically, this extension adds an option to the link
    context menu that allows you to pass the link to the Dr. Web AV
    service. I haven’t rigorously tested this or anything, but it’s an
    interesting concept that could be part of an effective multilayer
    personal security model.
  • FormFox
    This extension doesn’t do a whole lot, but what it does is
    important — showing a tooltip when you roll over a form submission
    button of the form action URL. Extending this further to visually
    differentiate submission buttons that submit to SSL URLs would be
    really nice
  • FlashBlock
    Flash hasn’t been quite as popular an attack vector as Javascript,
    but it still potentially could be a threat, and it’s often an
    annoyance. This extension disables all embedded Flash elements by
    default (score one for securing things by default), allowing
    you to click to activate a particular one if you like. It lacks the
    flexibility I’d like (things like whitelists would be very handy), and
    doesn’t give you much (any?) info about the Flash element before you
    run it, but it’s still a handy tool.
  • LiveHTTPHeaders & Header Monitor
    LiveHTTPHeaders is an incredibly useful too for web developers,
    displaying all of the header traffic between the client and server.
    Header Monitor is basically an add-on for LiveHTTPHeaders that displays
    a chosen header in Firefox’s status bar. They’re not really
    specifically security tools, but they do offer a lot of info on what’s
    really going on when you’re browsing, and an educated user is a safer
  • JavaScript Option
    This restores some of the granularity Firefox users used
    to have over what Javascript can and cannot do. I’d like to see this
    idea taken farther (see below), but it’s handy regardless.
  • NoScript
    This extension is pretty smooth. Of all the addons for Firefox covered here, this is the
    one to get. NoScript is a powerful javascript execution whitelisting
    tool, allowing full user control over what domains allow scripts to
    run. Notifications of blocked execution and the allowed domain
    interface are nearly identical to the built-in Firefox popup blocker,
    so users should find it comfortable to work with. NoScript can also
    block Flash, Java, and “other plugins;” forbid bookmarklets block or allow the ping attribute of the tag; and attempt to rewrite links that execute javascript to go
    to their intended donation without triggering the script code.

    The one thing I’d really like to see from this extension would be
    more ganularity over what the Javascript engine can access. Now it’s
    only “on” or “off,” but being able to disable things like cookie access
    would eliminate a lot of potential security issues while still letting
    JS power rich web app interfaces. Also read Pascal Meunier’s take on NoScript.

  • QuickJava
    Places handy little buttons in the status bar that let you quickly
    enable or disable Java or Javascript support. Note that this will not work with the latest stable Firefox ( Hopefully a new version will be available soon.
  • ShowIP
    This is another tool that isn’t aimed at security per se,
    but offers a lot of useful information. ShowIP drops the IP address of
    the current site in your status bar. Clicking on it brings up a menu of
    lookup options for the IP, like whois and DNS info. You can add
    additional web lookups if you like, as well as passing the IP to a
    local program. Handy stuff.
  • SpoofStick
    The idea with this extension is to make it easier to catch
    spoofing attempts by displaying a very large, brightly colored “You’re
    on ” in the toolbar. For folks who know what they’re doing this isn’t
    wildly useful, but it could be just the ticket for less savvy users. It
    requires a bit too much setup for them, though, and in the end I think
    this is something the browser itself should be handling.
  • Tamper Data
    Much like LiveHTTPHeaders, Tamper Data is a very useful
    extension for web devs that lets the user view HTTP headers and POST
    data passed between the client and server. In addition, Tamper Data
    makes it easy for the user to alter the data being sent to the server,
    which is enormously useful for doing security testing against web apps.
    I also like how the data is presented in TD a bit better than
    LiveHTTPHeaders: it’s easier to see at a glance all of the traffic and
    get an overall feel of what’s going on, but you can still drill down
    and get as much detail as you like.
  • All-in-One Gestures
    – merges the popular following extensions for management of mouse
    gestures, scrolling and power navigation. (Mix of Mouse Gestures,
    Rocker navigation, Tab scroller, History scroller, Link tooltip and
    Autoscrolling extensions)
  • Tabbrowser Preferences
    – a comprehensive UI for changing a number of the hidden tabbed
    browsing preferences in Firefox. It also provides the ability to
    control how internal and external links are opened in the browser and
    how the browser will react when links are sent to it.
  • Tab Mix Plus – More tweaks
    added to tabs. Ability to select and open muliple links in tabs, open
    link in a duplicated tab, merge tabs and close tabs from similar domain…
  • Duplicate Tab – allows you to clone a tab with its history and place the duplicate tab in a new window or in the current window.

  • Linkification – Allows Firefox (0.9+) to view plain-text URLs and e-mail addresses as actual links
  • IE Tab – can open the
    current page or a selected link embedding Internet Explorer in tabs of
    Mozilla/Firefox. Very useful for those IE only pages.
