Firejail not hiding files with Brave browser

If I run the following:

firejail brave-browser

And then try and access files in the browser (such as when uploading a file), Brave still has access to my entire home folder. Usually this doesn't happen with Firejail. I've tried it with Firefox, and it only gives access to the ~/Downloads folder. I've verified Firejail is running with firejail --list:

18974:daniel::firejail /usr/bin/brave-browser-stable

So I'm not sure what the problem is. The exact same command works with Firefox, so why isn't it hiding files with Brave? ## Environment * OS: Pop!_OS 21.04 * GNOME version: 3.38.5 * Brave browser: v1.29.81 (installed with apt)
