I just updated L5 and Firefox produces an error saying “Failed to read the configuration file. Please contact the administrator.” It gives to press OK, and then after a second it starts normally. If I close it and try to start it again it does the same. Any idea?

The issue with the firefox-esr-mobile-config package is that it is really outdated and does not support current Firefox ESR in PureOS Byzantium. There’s an old, pending MR on Purism’s gitlab, but that MR/ the version of the mobile-config-firefox project is also outdated by now. I just recommend you…

This does not help: https://support.mozilla.org/en-US/questions/1425490 because I can not find a folder called “pref”. The string general.config.filename exists in about:config and points to a file called mobile-config-autoconfig.js find ~/.mozilla/ -name mobile-config-autoconfig.js returns no…

[image] Firefox-esr after update Failed to read config file Librem 5 I can’t remember if PureOS for Librem 5 has the mobile-config automatically installed, but it was installed on mine. Removing it made the warning go away. To do that you can run sudo apt remo…

Thanks, but this configuration is supposed to do something useful. Not?

I don’t believe so, but if you’re concerned, you can always do it this way: uninstall firefox-esr delete the usr/lib/firefox-esr folder reinstall firefox-esr

Hmmm, I removed firefox-esr-mobile-config, now there is NO error message, but the interface has all elements and fonts tiny. So I guess this is what was this package about… What if I now re-install it?

Give it a try. If just reinstalling the mobile-config doesn’t work, give my post above a try. It worked well for me.

OK, so when I re-install the error returns but also the interface has larger elements as before. So it must be a bug in the PureOs packaging (I guess). Maybe next update will fix it?

Wait, do you mean that uninstalling firefox-esr, removing /usr/lib/firefox-esr folder and re-installing solves the issue and all has normal sizes on screen?

Nope. Unfortunately I just returned to the same situation. Elements on firefox are tiny. If I install again firefox-esr-mobile-config then again it produces the error. Uninstallation was sudo apt remove firefox-esr After that the folder /usr/lib/firefox-esr did NOT exist to remove So I re-insta…
