I use Firefox and have no issues. Don’t understand this. 
Be happy! Obviously you use a special Variant of Firefox! Maybe therefore you have no issues!
EOZ 
I also encountered slow loading of the firefox browser, whose password I had locked with a password. The message described above “The fix was to install : dbus-broker” only aggravated the situation, because the profile password had to be entered instead of once - many times when the application started.
I use cinnamon.
According to the logs, the culprit of the slowdown in the work of xdg-desktop-portal-gnome was determined.
The solution is described here https://bbs.archlinux.org/viewtopic.php?id=285590
The solution is to remove the package xdg-desktop-portal-gnome
i wonder why everyone have this installed anyway… it is only for GNOME installs… you may have choosen the wrong variant when it asks for xdg-desktop-portal-impl while installing flatpak or lutris…
I don’t use flatpak or lutris 
why this was installed is still a question…
I used to put xdg-desktop-portal and xdg-desktop-portal-kde in my user_pkglist.txt, but I stopped doing this when I noticed that they were bringing in xdg-desktop-portal-gnome and other dependencies such as libadwaita which I definitely don’t want on my KDE system.
I now install xdg-desktop-portal and xdg-desktop-portal-kde later on after first boot, and the only dependency they bring in is geoclue.
So it’s possible in some of these cases that xdg-desktop-portal-gnome has been installed as part of the 
installer’s approach to dependencies.
never saw this be installed on testing all the desktops…
and indeed if it asks for xdg-desktop-portal-impl the default option is gnome there… so in case it is called with --no-confirm it will install the gnome version if you do not select another one manually…
And same in cas eyou install it as a depedency of some package you do install it will also opt to choose one of xdg-desktop-portal-impl and defaults to gnome … so id you do not rerad and enter… it will went in too…
It was only installed when I had xdg-desktop-portal and xdg-desktop-portal-kde in my user_pkglist.txt.
I’ll test it again in a VM later…
as mentioned already
if you explicitly add implemention package it wioll not ask…
pacman -S xdg-desktop-portal xdg-desktop-portal-kde but calamares installes these packages from the list one by one i bet…
I don’t even get that when I install xdg-desktop-portal and xdg-desktop-portal-kde after first boot, presumably because xdg-desktop-portal-kde satisfies the “impl” requirement.
Looks like it does. I’ve finished a test install in a VM, and added xdg-desktop-portal and xdg-desktop-portal-kde to my user_pkglist.txt this time.
Here’s the relevant part of the install log:

This seems to be the problem.
UPDATE 
I tried again, but this time put xdg-desktop-portal-kde before xdg-desktop-portal in my user_pkglist.txt. The result was very different this time - only geoclue was installed in addition:

So that solves the problem for me 
but it may also be an explanation as to why so many have xdg-desktop-portal-gnome installed.

i bet not… not so many do use the user_pkglist option… it is more that users will may try installing steam proton flatpak… and do not see the question to choose one impl. while installing…

just see a dependency for cinnamon:
xdg-desktop-portal-xapp
that will bring in https://archlinux.org/packages/extra/x86_64/xdg-desktop-portal/ with xdg-desktop-portal-impl as a dependency…
no clue how to resolve this inside the installer… will need a detect and remove action …
@dalto @manuel ?
We should be able to just add the correct one to the package list. I don’t think we need to detect and remove.
That is because packages from the list are installed one at a time. But in the installer itself, packages are installed all at once.
Because xdg-desktop-portal was being installed first with --noconfirm, it was pulling the first option which is gnome for some reason.
Looks like installing xdg-desktop-portal-XYZ separately before installing xdg-desktop-portal will work without unwanted deps.
It is reasons like these, that I dislike using Mozilla Firefox packaged by any distro. I much prefer obtaining my copy directly from Mozilla and allowing it to automatically update.
I even made a script to download, extract, and place all the shortcuts (“Firefox Automatic Install for Linux”). https://gitlab.com/Linux-Is-Best/Firefox-automatic-install-for-Linux
It’s their loss if they don’t - user_pkglist is one of the killer features of (along with your good self of course ).
