Reproducible: Always Steps to Reproduce: 1. 2. 3.

I couldn't quite find the content to reproduce this but it looks like several other plugin window/tab event bugs. possible dupes Bug 223575 - events sent to wrong tab when running embedded Acrobat Reader Bug 231891 - controls in background tab of a quicktime plugin are active in foreground tab or second mozilla window Bug 233780 - Flash continues to respond to events (like mouseover) even on another tab not in the foreground.
