[Editcss] Can't install on Firefox 1.5

[Gregory Piñero]

Hi guys,

I try to install EditCSS 0.3.4 from
https://addons.mozilla.org/extensions/moreinfo.php?id=179

But I'm getting an error message that says:
Firefox could not install the file at

http://releases.mozilla.org/pub/mozilla.org/extensions/editcss/editcss-0.3.4-fx.xpi

because: Unexpected installation error
Review the JavaScript Console log for more details

Then in my javascript console it says:
installLocation has no properties
file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js
Line:  3391

Any help would be appriciated.

Much thanks,
