Change file picker in browsers

Hello!

So, is there a way to change the file picker in browsers?

Recently i have switched from Gnome Files (Nautilus) to Thunar.

Yes, i use Gnome.

I have used the command

xdg-mime default thunar.desktop inode/directory

So.

$ xdg-mime query default inode/directory
thunar.desktop

But then i noticed that file opener in browsers (Firefox-stable and Chrome) both are "Gnomish". I thought that it is Nautilus.

I went full speed and added

xdg-mime default thunar.desktop x-directory/normal

xdg-mime default thunar.desktop inode/directory

/.config/mimeapps.list

.local/share/applications/mimeinfo.cache

.local/share/applications/mimeapps.list

/usr/share/applications/mimeapps.list

Then i understood that it is not Nautilus, but Gtk File chooser.

Now i wonder if there is a way to use "native" Thunar and not this GTK file chooser?

I tried

GTK_USE_PORTAL=1 google-chrome-stable

No help.

I tried for Firefox

ui.allow_platform_file_picker=true

widget.use-xdg-desktop-portal=true

in about:config

(i did not know how to make it correctly so it looks like this)

Also no help.

I read there is some bug with it in FF, but what about Chrome then?

I use Firefox-stable as a main browser.

Found this solution but dont know how to implement it here
