Im not sure if their is something I'm missing but I cannot seem to disable the splash screen for the Portable Apps. I have a series of applications of my Portable Drive but not of of them are from PortableApps and as such I would like to have consitency in not having splash screens. This is a copy of my config. I have DisableSplashScreen set to true but it seems to have no effect.
[PortableFirefox]
FirefoxDirectory=firefox
ProfileDirectory=profile
PluginsDirectory=plugins
UserProfileDirectory=userprofile
AdditionalParameters=true
AllowMultipleInstances=false
SkipChromeFix=false
SkipCompregFix=false
WaitForFirefox=false
FirefoxExecutable=firefox.exe
DisableSplashScreen=true
As indicated in the readme, you need to place the INI file in the directory with PortableFirefox.exe. That's nearly always the issue. AdditionalParameters should be blank unless you want to pass "true" to firefox.exe.
Sometimes, the impossible can become possible, if you're awesome!
