1. Open the Firebug pane in your Gmail tab by clicking the Firebug icon.
2. Click the down arrow next to the Net tab, and select Disable monitor for mail.google.com

2. Click the Console tab.
3. Select Options.

Firefox Addons

As a web developer I often need a “fix”. No, not caffeine. Ok, well maybe I don’t need “the fix” but some of the web sites I inherit do or a new feature being implemented may have some conflicts so I need to do some debugging in order for the site to work correctly and in many browser types and versions.  Alas, I have a little army of grunt software that gets me from point a to point z much more quickly than sys.outs or alert messages. I’ve saved numerous hours using the following set of Firefox Plugins. I’ll briefly outline them and provide a link. My favorite is Firebug and YSlow is pretty damn cool also!

Firebug: You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page. Website http://getfirebug.com/

FireFTP: FireFTP is a free, secure, cross-platform FTP client for Mozilla Firefox which provides easy and intuitive access to FTP servers. Website: http://fireftp.mozdev.org/

FoxyProxy: FoxyProxy is a set of proxy management tools for Firefox, Thunderbird, Seamonkey, and Songbird: Website: http://foxyproxy.mozdev.org/

GreaseMonkey: Allows you to customize the way a webpage displays using small bits of JavaScript. Website: https://addons.mozilla.org/en-US/firefox/addon/748

IE Tab: This is a great tool for web developers, since you can easily see how your web page displayed in IE with just one click and then switch back to Firefox. Website: https://addons.mozilla.org/en-US/firefox/addon/1419

Screengrab: It will capture what you can see in the window, the entire page, just a selection, a particular frame… basically it saves webpages as images – either to a file, or to the clipboard. https://addons.mozilla.org/en-US/firefox/addon/1146

Web Developer Toolbar: The Web Developer extension adds a menu and a toolbar with various web developer tools. Website: https://addons.mozilla.org/en-US/firefox/addon/60

YSlow: YSlow analyzes web pages and suggests ways to improve their performance based on a set of rules for high performance web pages. Website: http://developer.yahoo.com/yslow/

Although an awesome feature I have to go to this page a number of times throughout the day because there is no way to configure the fetch to occur more or less frequently. When I forget to do check I may get an important email 45 prior to an auto-fetch when the email required a quick response. That’s where the solution comes in.

The solution does not configure an increase in auto-fetch of pop3 accounts in gmail but rather provides functionality to the Gmail Inbox interface so I can push one button to fetch (refresh) my Inbox page. Thanks to the script called GMAIL POP3 Quick Checker written by Tim Smart http://userscripts.org/scripts/show/51516 I can now effeciently keep up with all my emails. This script will add a “Refresh Pop3 Accounts” link just above the first email in Gmail’s Inbox of your account.

You first need to add the Firefox plugin from GreaseMonkey https://addons.mozilla.org/en-US/firefox/addon/748 and then go to the script and click the install button.

If you’re an avid FireFox (FF) user and you sometimes (ok often) find yourself asking yourself what a definition of a word is or to clarify a words ambiguous use in an odd context you may want to try Answer’s plug-in for FF. After you install the plug-in (a very simple process) you just need to use the ALT+Left Mouse click a word of a web page and the definition appears instantly as you can see in my snap-shot.
