Flatpak Firefox (and forks) very slow to start

SolarPunker@slrpnk.net to Linux@lemmy.ml – 40 points –

While other flatpak apps have no problems. Any suggestions?

Flatpak Firefox and Chromium are very different. Note that Flatpak Firefox starts normally fast for me.

Use the native version, it is one of the best maintained software and has access to "user namespaces" for isolation.

Now search on the internet what that is XD

The only "Firefox" not presenting this start issue for me is Floorp but it's proprietary.

Run it from the terminal to get more info.

Also run it through a profiler software like perf with the GUI hotspot.

Also, you are not by accident using secureblue, are you?

What is it? I'm on Bazzite.

Dont mind then. Secureblue uses a strange hacky workaround for manking Flatpaks supposedly more secure.

So then try the other things I said.
