This also affected userChromeJS( http://userchromejs.mozdev.org/index.html)

Steps to Reproduce:
1. Start Nightly with new profile
2. Install userChromeJS v1.5(http://userchromejs.mozdev.org/index.html)
3. Quit browser
4. Open the profile folder\chrome\userChrome.js with text editor
     And append the following 2 lines and save.
if (location == "chrome://browser/content/browser.xul")
userChrome.import("*", "UChrm");

5. Copy attached file to the profile folder\chrome\
6. Start Browser with -purgecaches

Mmm.  Yeah, for subscripts, the script filename isn't a URI at all.

I wonder whether we can drop that prefixing bit there...

Attachment: load subscripts

I'm not sure if I'm allowed to use C stdlib string functions. It seemed trivial enough without the ns*String hammer...

Comment on attachment 644795 [details] [diff] [review]
load subscripts

This seems fine, though please file a followup on getting rid of this hack if we can stop prefixing subscripts?
