When I click on the link: Search the online catalogus" in my Liberkey menu, I am getting an error stating: "No association for file extension".
I am getting this error since I am only using Firefox Portable (from within Liberkey). I am only using portable applications.
Probably i need to configure the file extension within Key Files Assoc, but I do not know which file extension.

Hello and welcome on forums.

Not sure have the solution for your problem.

In firefox : Have you in Options => Options => Applications have you an lbk option ?
Try to choose always ask then when you use it choose Liberkey menu for the protocol.

It can be a problem with your antivirus and firewall .
Can you precise what'is your configuration ?
You can use LiberkeyTools => Configuration => Technical information and Copy this information to the clipboard to put it in these forum.

In advance thanks.

Thank you for your reply, but I have gone back to the fix installation of Firefox. Suppose that a browserprogram that you use many times a day, can be a fix program.
