Can't flatpak run org.mozilla.FirefoxNightlyWayland: numerous "addons.xpi WARN Can't get modified time of ..." errors.

[kindaro]

I have ArchLinux on my laptop, so I believe flatpak is reasonably up to date: Flatpak 0.9.4. I wanted to run Firefox on Wayland, but it doesn't work, while Nightly and DevEdition do. I wrapped all the lines at width 80 for your comfort. % is my command prompt.

Looks like you have some addons installed. Please try the safe mode, to check if it is related to it.
@stransky any idea why the extension (I guess it's Pentadactyl: http://5digits.org/pentadactyl/ )is failing in wayland?

[kindaro]

To make things clearer, I removed pentadactyl from my system and repeated the test. I also repeated the test with -safe-mode command line flag. Neither makes difference.

I compared flatpak run org.mozilla.FirefoxNightly & flatpak run org.mozilla.FirefoxNightlyWayland and they say the same things to terminal but look very different. FirefoxNightlyWayland does not render anything. If I pretend opening a web page via keyboard, even if I don't see it, by the change of the window title I understand FirefoxNightlyWayland actually works the same as FirefoxNightly.

I am attaching a log & a screen shot.

What kind of DE you use?

[stozi]

looks like Sway (i3 for Wayland). I have the same problem on Sway in Void Linux. Works nicely in Weston though.
