I just upgraded my Firefox Portable to version 6.0. Now if I start the program, nothing happens; I get the flash screen, and then the program quits. (I also have Firefox Portable Second Profile installed, and it gives the same behaviour.) I tried starting in Safe Mode, with the same result, although I'm not sure if I did that correctly; I didn't find a Safe Mode executable, so I ran it from the command line and added -safe-mode to the end of the command. Also, no error messages (or feedback of any sort) appears when I run from the command line.
I'm running this (and other portable apps) off of a network drive on my employer's Windows 7 computers. (All of my other portable apps work fine, and Firefox only broke when I upgraded it from FF4 to FF6.) I initially did the upgrade through Firefox's own automatic system, but when it stopped working, I reinstalled from https://portableapps.com/apps/internet/firefox_portable (which is where my original installation came from). (The automatic update worked just fine when it upgraded from FF3 to FF4.)
Any advice? or any other information that I should give you? Please help!
PS: I forgot to say: The person at https://portableapps.com/node/28928 had what appears to be a similar problem, but there it was traced to modified add-ons. Although I have several add-ons, they are all straight from the Firefox add-on site, unmodified. (And that person could at least start in Safe Mode, unlike me.)
but if you say that all other programs work in your setup, then first thing I would try is simply to download the installation file again, check it for right MD5 sum to make all perfect and then simply install it over the existing again.
If this does not help, then I would personally create some new folder and try to install it completely fresh into it. No extensions etc. Try start , if works, fine then search for the bad extension can start.
Note that extension can cause many problems. It does not matter if you take them from the mozilla site. They are submitted by many people and they do not need to work as what they advertize. In some extensions some portable usage is not planned or not tested, so they will fail in some way.
If fresh install works, then you can try to copy to it your profile and see if it stops working too. If so we know where the problem is, to 95% within some of your extensions.
BTW: the update via the portable apps installer is still the preferred update method and not the use of the mozillas own updater.

I won't be able to try anything until I get back to the office on Monday, but now I have things to try, so I'll let you know how it goes.
When I got to work today, I started Firefox once more to check, and this time it just worked! (It did have to upgrade some add-ons, which is normal after upgrading Firefox.) So I don't know what was wrong or how it got better, but it works now.
