There are two active Firefox 4.0b1 icons in my Mac OS X dock.
My Snow Leopard dock has two active Firefox icons. They both have a glowing dot beneath (they are running) and when I command-click on them, they both point to the same Firefox app in my Applications folder.
This happened
Every time Firefox opened
== I installed 4.0b1

Same thing happening to me.
Maybe it is the plugin-container process (Out-Of-Process-Plugins), although I'm not sure if that process is already implemented on Mac.

Same thing is happening to me (one time I even had 3 firefoxs running in my dock!). It happens when I go to a page that has Flash on it. When I quit the second firefox app I immediately get an error that the flash plugin has crashed... Please help!

same thing too
I solved my flash issue just now -- what I did was uninstall the current version of flash. Then I downloaded and installed a previous version of flash (10r12_36). That seemed to have solved the issue, I'll report back if anything changes.
Here is the link to adobe's past versions of flash: http://kb2.adobe.com/cps/142/tn_14266.html#ionComHeading
