[Project_owners] "Unresponsive script" error when installing extension

[Stan James]

Hi everyone,

Since making the move to FF1.5, my script throws up a warning message 
after being installed, when FF is first restarted:

"A script on this page may be busy, or it may have stopped responding. 
You can stop the script now, or you can continue to see if the script 
will complete."

I don't know what "script" it is talking about, but some testing has 
showed that none of my js files had run before the warning came up. I've 
also tried leaving bits of the extension out, but I can't find a single 
culprit.  My only guess is that Firefox is doing some internal 
re-arranging, and the shear size of my extension makes this process take 
too long. (My extension is now pushing 750K) However, the FF1.0 version 
of my extension was 3.5MB and had no such problems.

Has anyone else encountered this? Any ideas on how to fix or work around 
it?

Thanks!
