Firefox Portable

I am trying to use FF portable as my default browser (Vista Ultimate 64bit). Everything works fine (add-ons, etc), except that if I try to open a _local_ html file I get the error message:

"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."

I can open a local file only if firefox is not already running. Below is my FFP ini:

[FirefoxPortable]
FirefoxDirectory=App\firefox
ProfileDirectory=Data\profile
SettingsDirectory=Data\settings
PluginsDirectory=Data\plugins

I am putting together a CD of MSDS files(.pdf) in a web page format. I need to have employees put the CD in and start "CBI\index.html" through FF Portable. All of our computers have autostart disabled. Can I use a start CD app file to do this? Consider that there are about 40 computers at my company and the CD drives are not the same drive letter.

I'm not sure what happened. I've been using (and LOVING) Firefox Portable for several versions and upgrading without a problem, but this time the update seems not to recognize my previous settings. They're still there in :\PortableApps\FirefoxPortable\Data\profile, but they're not being used -- I'm just getting the default look.

I want to firefox opening login screen password.
Can I do ?

Hallo,
bisher hatte ich schon Firefox auf dem PC, auch in deutsch. Wie kann ich beim portabel deutsch einstellen? Finde nichts in den Menüs.

Danke sehr.MfG

Found this extension: https://addons.mozilla.org/en-US/firefox/addon/3383

I haven't tested it myself, but you can take it for a spin. Post your comments.

I've found the instructions for installing them on FF Portable here, and I tried to follow them. I get errors downloading the Flash extension and I wasn't given the option to redirect the Shockwave installation. So I tried the "more geeky" instructions, but I couldn't find any of the files specified. Any help?

I have some problems with the Flash 9.0 plugin for Windows, which you can get here:
http://plugindoc.mozdev.org/windows.html#Flash

I can install the xpi and Flash works fine, but Firefox Portable doesn't install the plugin in /Data/plugins (even though this directory contains a text file that says "put plugins here").
Firefox Portable installs the Flash plugin on the c: drive.

Which files do I have to put in Data/plugins, the xpi or its contents?

This is what is says when I try to go go to Yahoo mail.
anyone know how to fix this problem plz ???
yes I have FFP 200.6
Sorry, Yahoo! Mail Beta does not support your browser.
You can either download a compatible browser or proceed to the original Yahoo! Mail.

I am trying to use Firefox from a CD. I got it to autorun and everything but now I am trying to get it to use the bundled Sumatra PDF portable as the default PDF reader. However, whenever I launch FFP, it grabs the profile from the Firefox installed on the machine, which happens to have Acrobat reader installed. When I am in FPP and go to the manage extensions screen, it shows all the extensions for the host Firefox, not the few that are included in FFP. How can I get FFP to use Sumatra from the CD?
