Firefox Portable

As from last week, the Firefox PortableApp is no longer starting. When I click the icon, or try to start it from its folder, I see the startup window (that says Mozilla Firefox Portable Edition) but then nothing more.

There does not seem to be any avaliable updates, I am running PortableApps v. 11.2 and Firefox v 28.0. My other portable apps works, so this seem to be a specific Firefox PortableApp problem. I have tried it on another computer but had the same problem. I use PCs.

Since the latest update, that's the error message I get about 15 seconds after the boot splash - FF GUI never even appears prior to the error box.

I am from Germany and Gema block youtube here. first i install hotspot shield software to access youtube, but it hang my computer. Then i use a web proxy website http://proxymonster.us i was reading somewhere that there are some chrome or Firefox addons for unblock restricted website. I search on google but didnt find the correct one. Do any body know about any addon or plugin for unblock youtube.

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.
