Hello, Recently, I updated ubuntu to the latest version, and had set Firefox as my primary browser (as I normally did). I, however, could no longer access to the local hidden directories, i.e.: .local, etc., with this version. I even tried to disable Firefox sandbox security, security.sandbox.content.level = 0, and changed chown/chmod to the lowest levels, but those didn't help. The issue can be repeated via the URL in Firefox as followed: file:///home/y2021x/.local or any other hidden directory. I could open these files/directories in the older versions of Firefox. Am I overlooking something? I appreciate very much if you could help me find out the solution to this problem. Thank you very much.
