Just a guess, but maybe another script is setting the frame to
undefined or null.

You might find it easier to use a singleton JS module instead of a
singleton XPCOM component. Concerning killing of the thread, thread
manangement from extension javascript has been notoriously difficult
in the past. It might be easier (albeit not more performant) for your
thread to periodically check if any navigator:browser windows are open

I think you forgot a step. According to:

after the step you did above, then do:

I've been tinkering with evalInSandbox, trying to figure out which
scenarios are unsafe. According to [link],

Toolbar button events - oncommand and ondblclick

2010-01-03T20:49:28Z

Hi All,
I have a toolbar that has a couple buttons that must handle the click and
double click events differently. In other words the command handling logic
is different for a click event and double click event. The problem is that
when I do a double click I still get the single click event. I have tried

I have finally found some documentation after reading this thread:

I am now using an XPCOM object that has a function startup(data) which

the first call, it sets a variable firstrun to true, so that it is

Of course. I should have been more careful.
No guessing. I just had to look at the webpage.

After reading this paragraph, and before reading the rest of the

I had considered it when first writing the code but had decided on the
wrong code somehow.
Thanks again,
