Flatpak Firefox (and forks) very slow to start - SLRPNK

While other flatpak apps have no problems. Any suggestions?

Native packages? Sorry.
Sorry for what? I’m trying a fresh install of Bazzite so the distro prefers flatpaks.

Probably best that you do the same (installing packages in the FS overlay kind of starts to defeat the point of containerization). You could try installing it with a distrobox and then exporting the app—see if that fixes your loading issues.

I run Bazzite on a gaming laptop from 2015, and I haven’t noticed any particularly long load times. Do you have some browser extension that are maybe causing issues?

My only extension is uBlock Origin but it isn’t the problem (I uninstalled it to test and nothing changed). Thanks for your suggestion, I’ll try to play with distrobox (I’m new to Bazzite and immutable distros).
You can try rpm-ostree to install in the lowest userspace layer, but Bazzite purposely switched to flatpak Firefox and discourages installing software using rpm-ostree, unless you absolutely have to.
Oh I forgot about rpm-ostree ty! In this case of flatpak not working it is suggested rpm-ostree or distrobox?

Recommended installation order is:

  • Flatpak
  • Distrobox
  • Rpm-ostree

toolbox should also be installed on your system, and it works similarly to distrobox, but I’m less familiar with it.

Thank you!
