Yes, see this page for examples.

Edit

XPCOM and so nsIFile are now legacy technologies :

Use of OS.File is preferred over the examples in this article. Only use these legacy interfaces if OS.File is not available to you.

You can find the new way to go here

mozilla will be deprecating XPCOM and therefore the nsIFile so this will very soon be irrelevant.

Note that this is still valid for Thunderbird, which is not (at least not yet) deprecating/removing "legacy" extensions. In addition, there are various forks of Firefox in which "legacy" extensions are still valid.
