Palemoon64 and Waterfox64 do not have this popunder issue because neither loads the Flash app. Both just use the Flash DLL via the plugin-container app. The plugin-container app is running at the medium integrity level just like the user. I wonder what the security implications are. Is this as safe as the sand boxing of the Flash app?
Edit: so far, I'm liking Pale Moon's traditional (default) status bar... even if you do lose a bit of browser viewing area.
This issue's been bugging me since Firefox 18. I'm just glad that I'm not alone!
I never could locate the exact reason - other than:
loading the flash plug-in into a new window = "popunder".
It is quite repeatable once you know how to set up the conditions.
Anyway, I'm lucky in that:
1) Firefox is not my main browser (IE is)
2) I only need Java and Flash to work in Firefox (no add-ons)
3) lehnerus2000 suggested Pale Moon
I had played with Pale Moon before I had 64bit OS to work with... but now I've replaced the traditional Firefox with the Pale Moon 64 build (heed the warnings in the link before making the leap).
In theory, Pale Moon 64bit should consume less RAM and CPU power when streaming flash based video (which I do a lot). The 64bit plug-in app uses the Flash DLL directly. This is not true for the 32bit plug-in app (even Pale Moon's 32bit build).
I'm not going to mark this thread as solved since moving to Pale Moon 64bit is not going to work for most. And such a move does not solve the "popunders" within the Firefox 32bit or Pale Moon 32bit.
