Description

[Pascal Chevrel:pascalc (PTO until April 26)]

Mozilla/5.0 (X11; Linux x86_64; rv:63.0) Gecko/20100101 Firefox/63.0 ID:20180802220056 + Ubuntu 18.04

When started from the terminal, Firefox outputs a bunch of warnings:

This is AFAIK, a recent regresssion but mozregression suppresses the browser output to the terminal so I couldn't find a regression range.

We're unsure what we should do with this, so leaving it open for now. Martin, if you could advise on whether we should file something elsewhere, we could just close this here.

Looks like gtk-contained.css lives in gtk-land: https://github.com/GNOME/gtk/blob/83a80ab86640c4b24698c9755e9699ae3cce0d33/gtk/theme/Adwaita/gtk.css

[Martin Stránský [:stransky] (ni? me)]

Sure, I can handle that.

[Martin Stránský [:stransky] (ni? me)]

Pascal, 

- do you have any custom gtk3 tweaks? like ~/.gtkrc* file?
- can you try another gtk3 application from terminal? (gedit for instance).
- can you test different gtk3 theme? You can switch to "Adwaita" at gnome-tweaks application.

Hi Martin, I don't have gtk3 tweaks and gedit produces the same error. Switching to Adwaita indeed fixes it so that's a bug with the theme I was using. Thanks for your help, I am going to mark this bug as invalid :)

A part of this bug is still present under some conditions, see bug #1516101 for details.
