As the result of upgrading to the 22.04 LTS, the behavior of ff's downloading has changed. I've read a few posts about this, but haven't seen anything relevant to solving my problem. Specifically, I want ff to download all files to `/tmp/`. In the `Settings` tab using the `Browse` method, I select `/tmp/`, but it the setting then shows  `/run/user/1000/doc/fa9c1cc2/tmp⁩`. If I try using this set up, the downloads fail. If I use `~/Downloads`, it works, but that's not what I want.

Can someone tell me how to ff to download files to `/tmp/`? Below is a screen shot of my `about:config` settings:
