PORN WARNING
I can force Plugin Container crashes simply by increasing page Zoom level on pornhost.com.
Never thought to attribute it to FlashGot.
Let me see if I can find a "tame" page.
If I can dup in -safe-mode (unless -safe-mode disables Plugin Container?) then I was going to file a bug.
Search:
http://www.google.com/search?q=http%3A%2F%2Fwww.pornhost.com%2F+0068138732&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:unofficial&client=seamonkey-a
Top link should be:
http://www.pornhost.com/0068138732/
Set zoom level on pornhost to be 150%.
(That is important cause you
really want to see the action

.)
Kidding aside, it is important to increase the zoom level.
Also having Adblock Plus enabled, blocking page adds could be important too?
When I open the page, the Flash, the plugin area, is topmost on the web page. Top & center. (If Adblock Plus was not installed, there would be ads above the Flash area.)
(Also note that
sometimes Live Jasmin gets by too. But then I'm sure it's set to fire - only sometimes.)
Open the link
from the Google search.
Also make sure that Tabbed Browsing,
switch to new tabs opened from links is not enabled. (IOW you do not want the link to have focus when you open it from the Google search.)
Now jump to the opened link.
(pornhost.com Allowed, & Flash Allowed)
Plugin Container should crash.
This is on the (SeaMonkey) Trunk.
(Actually thinking FF
could be different in this area, not sure?)
