Hello,
I've been fighting an issue with an web application we use at our
business (large tech company), for over a year now. This web
application launches a Java application, and immediately after the
application launches, it crashes. I downgraded java to 1.6.0.15 and
noticed it worked again. However, there are other web apps that now
won't work with 1.6.0.15, so I've dug it a bit deeper. After much
troubleshooting, I've discovered the problem ONLY happens when the
GreaseMonkey extension is enabled. If I disable it, the app works
just fine. I've tried enabling it and disabling all scripts, to no
avail...still have issues.

My environment:
Toshiba M11 laptop
Linux Mint 12 inside a Virtualbox environment, where Win7 is the host.
Firefox 12.0 (but has happened on many previous versions)
GreaseMonkey 0.9.18
Which script is being used is irrelevant, and it happens when all
scripts are disabled.
I cannot provide an URL because it is internal

I really love using GreaseMonkey, but may need to part with it if I
can't find a fix :(

Thanks,
Jim

Sounds like https://github.com/greasemonkey/greasemonkey/issues/1333 -- but back then upgrading to Firefox 4 fixed it.

The best thing you can do to increase the chances of this getting fixed is provide a good simple test case.  Make the smallest possible web page with the smallest possible java app(let), with which you see this behavior.  That provides us something to test against.

Anthony,
Thanks for the quick reply. Unfortunately, in this case, the app is
very complex, and I'm not the developer so wouldn't even know where to
start. It opens up several Firefox tabs before it actually kicks off
Java.

I've even enabled Java tracing/logging and it doesn't show anything of
interest...just an abrupt stop.

Jim
