I am very pleased to announce that I have completed this project. It was actually very simple to do, and the only thing is I can't get the logo to display correctly, so it's using a basic logo.
To install:
1. Download the file here:
http://www.filesavr.com/rcdb2. Find your Firefox profile on your computer. It should be in a directory similar to this:
C:\Documents and Settings\<user name>\Application Data\Mozilla\Firefox\Profiles\
**Note that the Application Data folder is hidden and you won't find it unless you change the view settings Windows Explorer.
To view hidden folders:
1. On the menu bar (under the title bar) go to Tools and select Folder Options.
2. Click on the View tab and in the Advanced Settings area, find Hidden Files and Folders. Check "Show Hidden Files and Folders"
3. Your Firefox profile name will be a string of random numbers and letters. Select the one you have been using (likely the default, and there should be another name appended to it to mark it otherwise).
4. Open the searchplugins folder and copy the file you just downloaded (rcdb.xml) into there.
5. Restart Firefox and this should work.
Any questions, please email me.
