When I am on a site with flash player, such as YouTube, the flash player window appears on all tabs.
When I am on a site with flash player, such as YouTube, the flash player frame pops up on all tabs. If I go to another site, the flash player frame remains on all tabs and is black. The only way to get the frame to disappear is to delete the tab in which the flash player frame was originally opened, or to exit and restart firefox.
This problem exists with any version of firefox 6 and later and flash player 10.x and 11.x. This only occurs on my Linux workstation installations.
Has a fix / work-around been identified?

Could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Edit > Preferences > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
Unchecking the "Use hardware acceleration when available" and restarting did not change the outcome. I also browsed the about:config options to see if there were any other related graphics options, but nothing else seemed to fit.
You could try updating your plugin to 11.2.
Apparently there's no native graphics acceleration for the Flash plugin on Linux (Adobe Forums: FP11 Linux Hardware Acceleration?).
I think there is a way to specify whether a specific plugin runs in Firefox.exe or plugin-container.exe, but my memory is hazy on that point. I think the relevant preferences in about:config start with dom.ipc.plugins but I'm not aware of an authoritative current source for how they work.
