Firefox Portable

I copy the file NPSWF32_12_0_0_77.dll in E:\PortableApps\FirefoxPortable\Data\plugins and when i test the plugin on adobe test page it shows that i have flash plugin installed but when i try to play a flash video Firefox freezes. Why is this happening?

I selected Firefox Portable so I could run it on my PC (Windows 7) in drive D (secondary hard drive) and avoid excessive writing to primary drive C (SSD). I'm trying to find where history and other data are stored so I can use CCleaner to occasionally securely overwrite it. I've searched the various Firefox files on drive D and have been unsuccessful in finding the specific file that stores this information. I know it is being stored because by clicking on the Firefox tab and selecting History, I can see the list of sites I visited today and yesterday.

Can i upgrade portable Firefox this way: Install Firefox in Program Files from original setup file, then copy all files from the installation directory to E:\PortableApps\FirefoxPortable\App\Firefox?

hello,

INTRODUCTION :
firefox too long ( one of the three best web browser ) does not work anymore it is not tolerable . (3 bug is present , * does not start * runs for less than a minute then freeze * windowed mode without failure)

on (more than 3 ) virtual machine it works very well

I 'm only talking about windows 7 integrale x64 ! fully updated via windows update!

the problem is recurring since 6 ( a bit more ) last firefox (currently tested with 27.0.1 )

this is not normal! firefox does not work because paleMoon works!

I have these two files from portable flash player put in CommonFiles/Plugins:

NPSWF32.dll
nppdf32.dll

How to make Firefox locate and use them?

First search box stopped, then cant load videos,mouse and dial constantly flickering, re-installed still no good .Moved to chrome, not my favorite but no choice ?

I use Firefox 27.0.1 stable (non-portable) as my everyday browser in windows 8.1 x64.

I have also installed
FirefoxPortableNightly_30.0_Alpha_1_Pre_English_online.paf

All works ok, but, if Nightly Portable crashes
and you press "Restart Firefox" in the Mozilla Crash Reporter window
(the crash report is submitted before it restarts)
then, when it restarts, it loads the profile of my Firefox 27, instead of the Nightly Portable one!

Please fix this issue.

Currently, it's impossible to install FirefoxPortable while an instance of FirefoxPortable is already running, due to this alert:
---------------------------
Mozilla Firefox, Portable Edition | PortableApps.com Installer
---------------------------
Please close all instances of Mozilla Firefox, Portable Edition and then click OK. The portable app can not be upgraded while it is running.

ОК Cancel

Is there any way to prevent FirefoxPoratable from reading the registry? I have tried the ini file and all its settings with no luck. I have also tried profiles without success. I need to run Firefox with an old version of Java for internal use and leave the local copy set to the latest version. No matter how I configure either the settings from one change the other. And the registry is always read and the plugins registered there are used by both and across all profiles.

When I click on the link to the prior versions it takes me to the latest version and there are no other option that I saw to download an old version.
