I'm in Ubuntu 22.04, logged in as user-me. I would like to open /home/user-other/path/to/index.html with firefox. user-me is in the group user-other, and everything under /home/user-other has permission 755. I can open /home/user-other/path/to/index.html in the terminal without problem. If I simply type /home/user-other/path/to/index.html in the address bar of firefox, it gives "Access to the file was denied". If I open the file with the file picker, the page is loaded, but as "file:///run/user/1000/doc/some-hax-number/index.html", and the resources in the page are not properly loaded. How can I properly open /home/user-other/path/to/index.html?
