Firefox Portable

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.

Hi,

There is a list on the Bleachbit(open source cleaner app) for Firefox about what to clean:

Hello everyone,

I have some Problems installing the Shockwave Plugin for Mozilla Firefox Portable on my pendrive.

I have read the instructions on your Page:

https://portableapps.com/support/firefox_portable#plugins

But the Problem is that the Shockwave installation routine doesnt let me direct the installation. It just installs Shockwave to the harddrive so i cant direct it to the pendrive.

I've been using Firefox Portable for a while now and have not experienced any kind of error until yesterday.
since i Updated My Portable Firefox to the latest Version (27.0.1), when i click on Firefox Logo to RUN it, Showing This Error >

After downloaded the Firefox 27.01 version I checked it for virus.

Avast 8.0.1497
Virus definition 140213-1
Released 2014-02-13 19:17:43
Found: Threat:Win32:Malware-gen inside the plugin-container.exe

Is it just me or has anyone else noticed in FF27 the jumplistcache in the profile folder does not empty when
firefox is closed even when set to clear everything on exit.
I also have FF24 and no problem there.
