hello, what you can do is to copy the flash plugin .dll file from a pc that uses the up-to.date versiom (at my pc it's located in C:\Windows\SysWOW64\Macromed\Flash\NPSWF32_11_2_202_235.dll) & put it in the \Data\plugins folder of the portable firefox. in case shockwave flash is showing up twice in firefox > addons > plugins, afterwards, disable the older version...

Thank you, this works nicely. I would not have thought that the mere presence of a dll would lead to a working plugin.

you're welcome - please note that for the 11.3 version of flash you'd have to copy both the .dll file & the FlashPlayerPlugin_11_3_XXX_XXX.exe (which is used for adobe's protected mode) into the plugin folder, otherwise firefox will hang on pages with flash content.

That's what I just noticed. :)

Unfortunately I found that the problem is only partially solved. Since I have done it the way you described, a window sometimes pops up containing the following:

Plugin Container for Firefox no longer works

The window apparently originates from Windows itself; it is one of those "Program xyz no longer works"-windows that offers you to search for a solution online and/or close the program.

firefox 13.0.1 did contain a fix for a certain plugin container crash - i'm not sure if it also applies in this case, but you could certainly try updating the portable version and see if the issue goes away

Just done so, thank you. We will see what the future will bring, but in the meantime I also read about the latest Flash Player being crashy in FF 13.0 and this being fixed in 13.0.1, so it appears likely that this will fix it.

In Firefox 14 (this may work on other versions) to disable the yellow drop-down nag bar concerning a plugin update when you know your current plugin is working fine.

1) Go to a new tab blank page

2) type "about:config" in the address bar and press enter

3) click on OK on the warranty nag (if you haven't already checked don't show again)

4) scroll down to: plugins.hide_infobar_for_outdated_plugin

5) double click to change to true

6) close the browser completely

7) restart FF and go to a page using the outdated Flash plugin

yellow nag bar is gone

This doesn't mean that you don't the need to update. There are probably useability, security and vulnerability reasons to update.

But until Adobe and Macromedia (two of the greatest offenders) get their crap together and provide useful updates that work without crashing your PC, jumping through hoops or annoying the hell out of us this will suffice.
