Firefox addon-SDK addon not writing files (but works in jpm)

I'm scratching my head here...

I wrote an sdk addon that uses OS.File to write a text file.

It works fine using jpm run

However, when I install it into Firefox as an xpi

Then even my console log messages don't show up in the console.

But it still runs, I can debug it (it has a timer loop and so I see it pause on the timer when I set a breakpoint in there)

The code seems to run fine except for:

  • the console log messages not being displayed
  • the file not being written

What I mean by code running "fine" is the variables all seem to get filled correctly in the debugger and the execution seems to occur correctly (breakpoints work)

My extension doesn't make any visual modifications to the page. So I don't know if that part would work correctly or not, but I'm just concerned right now about the failure to log and to write files.

anyone have any idea what could be the problem?

jpm run sets different log levels compared to a regular firefox profile. relevant docs

the file not being written

depending on where you do your calls to OS.File e10s may make a difference due to content sandboxing. Try toggling that. If it does make a difference then you're using file IO in a context where you shouldn't.
