Ultimately I ended up doing a clean install of Firefox and then everything worked fine. I know a “clean install” sounds scary but these tutorials walk you through it and you get to keep everything that’s important (except extensions, you’ll have to reinstall those).

-Mozilla Forum – installing FF 1.5 and how to do a clean install

Background Info
Specifically the problem I was having is that EditCSS wouldn’t install. Here’s what was happening:
I try to install EditCSS 0.3.4 from

https://addons.mozilla.org/extensions/moreinfo.php?id=179

But I got 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

I’m guessing that the underlying problem was that I had uninstalled that extensions when I upgraded because I uninstalled every extension when I upgraded to 1.5 because I was getting a gray box in Firefox (Also covered in above link).
