Permission denied when trying to associate extension with program
I just updated to Firefox 67.0, which I am using with Ubuntu 16. I'm trying to associate a file extension with a program. I click on the link to file with the new extension, and Firefox prompts me to say which application I want to use. The problem is that the extension is located in the usr folder, and Firefox complains that it hasn't got access permission.
What do I do? Thanks in advance.
