Firefox = on Launch Loads Tabs Very Slowly

I have 20+ tabs open. When I need to reboot, or close Firefox, for whatever reason, when I launch it again, it launches fast and all 20+ appear quickly.

But then to load the content therein takes approximately forever. Once that initial load happens, then new tabs load quickly, as expected.

I do not have xdg-desktop-portal-gnome installed. I use Xfce. Everything is up to date, and this problem has existed for a long time, probably years.

I do have Flatpak:

$ pacman -Qs 'flatpak|portal'
local/libportal 0.8.1-1
    GIO-style async APIs for most Flatpak portals
local/libportal-gtk4 0.8.1-1
    GIO-style async APIs for most Flatpak portals - GTK 4 backend
local/xdg-desktop-portal 1.18.4-1
    Desktop integration portals for sandboxed apps
local/xdg-desktop-portal-gtk 1.15.1-2
    A backend implementation for xdg-desktop-portal using GTK
local/xdg-desktop-portal-lxqt 1.0.2-1 (lxqt)
    A backend implementation for xdg-desktop-portal using Qt/KDE
    Frameworks/libfm-qt

Any suggestions?

Re: Firefox = on Launch Loads Tabs Very Slowly

Normal  and intended, Firefox just launches "shortcuts" and will only actively (re-)load a given tab on access. If you want to instead wait forever for the mainwindow to appear while it's busy loading all your tabs:

I think there's a setting to enable loading regardless but not entirely sure where yet set "browser.sessionstore.restore_tabs_lazily" to false in about:config

Re: Firefox = on Launch Loads Tabs Very Slowly

I don't think that's my issue. What I do is, when Firefox launches, is to visit every tab quickly so they will start to load. That's when it takes forever to load.

The main window, meaning the app itself, comes up fast.

The content of each tab, whether I visit each, or I select all and do reload, takes a very long time.
