I think it might work if you manually add the protocol to the file where Firefox stores this information: # Type "about:profiles" in the address bar # Find the profile listed as being "in use", and click the "show in Explorer" button in the "root directory" field # Open the folder that appears, find the "handlers.json" file, and open it. Next, you want to add an entry for the SSH protocol. At the end of the file, you should see several characters like this: <pre> }]}}} </pre> What you want to do is add a comma, and insert the snippet below, so that it matches this: <pre> }]}, [snippet below] }} </pre> Replace [snippet below] with the following: <pre> "ssh":{"action":2,"ask":false,"handlers":[{"name":"SecureCRT","path":"C:\Path\To\Application"}]} </pre> Replace "Path\To\Application" above with the location of the SecureCRT executable. Once you've done that, save the file, and then restart Firefox. Type "about:preferences" in the searchbar, scroll down to the "Applications" section, and look for the "SSH" entry. Under "action", you should see "Use SecureCRT", and if you type an ssh:// url in the address bar, it should work now. I don't have a copy of SecureCRT installed to test this with, so I'm not completely sure if this will work or not. Let me know what happens! (If if doesn't work, you can just remove the entry from handlers.json and restart Firefox again).
