I'd like to open a webpage upon login on Mac. What i did so far: - I saved the url location from firefox onto my desktop. It's a .webloc file. Firefox can open this file at this point. - Firefox is set up as my default browser. - Added the webloc-file to my startup list on my Mac useraccount. Then i try. The website will open, but it uses Safari instead of Firefox (firefox is still default browser). Next thing it tried: - Associate .webloc files to open with Firefox by default instead of Safari (that appeared to be the problem). - PROBLEM: Mac/Firefox won't let me use Firefox as default application to run webloc files with. How to solve this?
