Custom Geometry 1.2.0 for Firefox

Custom Geometry is an extension which resizes and positions the window according to your settings.
Custom Geometry adds a button to the Firefox status bar that will resize the Firefox window to your specifications. Many other extensions will resize the window, but only to preset dimensions, such as 1024x768 or 800x600. Custom Geometry will set the window to an arbitrary size.
I needed this functionality because I prefer my browser window to be in a particular location and size on my screen. Since Im using Microsoft Windows XP, the prospect of the browser window staying where I want it is dim. A video game, misclick, or even just a popup window (usatoday.com anyone?) will resize the window. Now, a single click gets it back into place.
Instructions:
1. Open the CustomGeometry-1.0.0.xpi file in Firefox 2.0.
2. Choose to install the extension.
3. Restart Firefox when instructed to do so.
4. Open the addons window by clicking "Tools," then "Add-ons."
5. Select "Custom Geometry" from the list.
6. Click the "Options" button.
7. Set the window geometry options that you prefer.
8. Hit "OK" to save your preferences.
9. Click the new icon on the lower right right side of the status bar to apply these settings at any time.
Enhancements:
- Added support for Thunderbird.
- Fixed a case issue causing the icon not to work under case-sensitive filesystems (Linux).
