Greasemonkey User Script for Lets Run Message Boards

I can’t be the only person that thinks the letsrun.com Message Boards are in serious need of an update. I realize they work just fine and they are quite popular, but the usability of the page is stuck in the late 1990s. In fact, it could almost be nominated for Web Pages that Suck, which is actually a great site for web developers to discover what NOT to do. The site’s content is great – don’t get me wrong – but the design and usability could use a little work (and that’s what I’ve done).

Stock Charts Firefox Extension

This extension has been updated for Firefox 1.5 and is available on the Stocktickr Blog. Stocktickr is a new social trading site.

Install the Stock Charts Firefox Extension, or continue on to read more about the extension.

Background:

I am looking at stock charts quite frequently. I used Firefox’s bookmark keyword feature to create a quick way to go to a stock chart for the ticker I wanted. For example, to go to the stock chart for Microsoft (MSFT), I type in the following in my address bar:

c msft

The “c” is my keyword shortcut for the following url:

http://stockcharts.com/def/servlet/SC.web?c=%s,uu[w,a]daclyyay[dc][pb9!b50!b200!d20,2][vc60][iUb14!La12,26,9]&pref=G

Firefox automatically replaces the %s with “msft” after I hit enter.

This works well and is a nice feature of Firefox. However, sometimes I want to view the charts of several stocks at the same time. For example, there are stocks listed at three of my favorite stock related sites: Poormans Investments, Trader Mike, and Kirk Report. Ideally, I’d like to put the stocks listed there in their own tab so I can quickly compare. While it is possible to do this with my nifty keyword shortcut, it takes far too much clicking and typing.

A Better Way

I thought I would try my hand at creating a Firefox Extension for doing what I wanted. Enter the Stock Charts Firefox Extension.

I created an extension that lets you select muliple ticker symbols in a web page seperated by spaces, commas, newlines (or all of the above) and then open a tab with a stock chart for each one. By default, you can choose from stockcharts.com, yahoo.com, or bigcharts.com. You can customize these or add your own.

Once the tabs get created, you can easily go to the next tab using the Firefox Keyboard Shortcuts, ctrl-TAB to go to the next tab and ctrl-shift-TAB to go to the previous tab. Use ctrl-W to close the current tab.

Also, of course, this extension isn’t limited to stock charts. You can add a custom item to the menu to take you to any web site you want – maybe to Yahoo!s message boards for each symbol you select or a Google search for each word in text you’ve selected.

Thanks to the Define Word extension which I borrowed from heavily to create this.
