I've just posted a pre-release of Firefox Portable 3.0.11.1 Revision 2. This has a fix for the SFTP cache issue mentioned here.
BUG BACKGROUND: If you use SFTP, it prompts you to cache the key in the registry on first connection to a new server. Until now, we've been telling people not to cache keys. But, some people don't know and do anyway.
FIX: The registry key is now saved and restored.
INSTALLER FIX: The PortableApps.com Installer was updated to 0.9.9.5 Pre-Release 1 to fix issues with free space calculation and warnings when compiling.
Download: Download FileZilla Portable 3.0.11.1 Revision 2 Pre-Release 1
3.2MB download / 2.9 - 6.9MB installed
MD5: 97d91adced93573807b2e0f1eeee9f2c
Please give it a good test with SFTP sites and let me know how it works. I'd like to release this tomorrow.
