Readable search results: http://mxr.mozilla.org/mozilla-central/search?string=chrome%3A%2F%2Fbrowser&find=%2Ftoolkit&findi=&filter=^[^\0]*%24&hitlimit=&tree=mozilla-central I don't think filing a bug like this is a good move. Most of the search hits look OK (mostly testing code), the non-obvious ones are scattered across a few components (devtools has most hits, plus a few here and there). For each component this issue should be discussed separately. I'm going to pick one component - devtools and see what happens.

For the case of DevTools, there are matches in the following files: * /toolkit/devtools/gcli/commands/security.js * /toolkit/devtools/shared/profiler.js However, those code paths are only used in a browser context today. I agree that in principal it is incorrect for /toolkit files to reference a specific application. For DevTools, this would only become important if non-Firefox wants to display our front end UI. Keeping the bug since that we may eventually support such a goal. I would suggest making separate bugs to report this issue outside of DevTools (if you wish to do so).

OK, gotcha, I was burden when compiled it into omni.jar and reporting error. And if 912121 are fixed, then this won't be a problem anymore:) I would take of it.
