It is not the password issue that HG suggested. Nor is it an issue with specifically trying to open a file rather than have a directory open in jupyter. The issue is that Firefox claims to not be able to read the file that it is passed. But the file exists with suitable permissions and if I use ```Open File...``` Firefox **can** access/read the file. It used to be that when I ran ```sage -n``` or ```sage -n jupyter file.ipynb``` either the directory or the specific file, respectively, would successfully appear in the tab that opens in Firefox, but now I am getting the > file not found error.
