I can confirm this issue: Using Firefox 14.01 and using utils.import to load
user scripts from the Firefox profile directory does not work as expected:
Changes to the imported files do not take effect after a Firefox restart. I
also tried unload without success:
Components.utils.unload("file://" + filePath);
Components.utils.import("file://" + filePath);
However, sometimes (I cannot reproduce when exactly) after several restarts
Firefox seems to drop the cache and read the file again. I'm curious for any
workaround. It would be cool to reimport a modified file without a restart.
This is a function of the "startup cache" which improves startup
performance by cacheing preparsed versions of these files the first time
they are parsed to improve future startup times. The startup cache is
automatically cleared when Firefox updates to a new version, when the
user launches in safe mode, and I believe whenever a non-restartless
addon is installed or uninstalled. You can programmatically clear the
startup cache using the nsIStartupCache.invalidate() interface; you can
also do some other things:
* Use the -purgecaches command line argument or MOZ_PURGE_CACHES=1
environment variable to clear on startup.
* set the MOZ_STARTUP_CACHE=/path/to/file environment variable to change
what file Firefox uses for the startup cache
