1785278 - AutoConfig in Snap and Flatpak

Status: RESOLVED FIXED

(Core :: AutoConfig (Mission Control Desktop), defect, P3)

Description

[Simmo Saan]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:103.0) Gecko/20100101 Firefox/103.0

Steps to reproduce:

Followed https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig to set up /usr/lib/firefox/firefox.cfg before Ubuntu 22.04 upgrade changed it to the snap version.

Actual results:

Previously set up AutoConfig is ignored.

Expected results:

AutoConfig should also work with the snap version.
According to https://forum.snapcraft.io/t/firefox-snap-no-longer-reads-usr-lib-firefox-for-customization/29713/20 it works for policies. If /usr/lib/firefox is not an acceptable place for such modifications, then some other path should be allowed for AutoConfig in snap.

So one thing I always wanted was to set a path for autoconfig and read it from there.

Something like that would fix this (you could just put the file in a place that could be read by the Snap.)

So we are going to support reading AutoConfig file from more than NS_GRE_DIR, i.e., /etc/firefox/

Mike, do you think we need the same for Flatpak?

Comment 8

[Mike Kaply [:mkaply]]

Yes, probably. Should we do it in here or a separate bug?

Ideally we would have a way to check if we are in a package generically.

Hey guys, isn't this a hack to bypass administrator system policies? Setting MOZ_SYSTEM_DIR to my own directory ignores the policies in /etc/firefox for example. That's not good I presume.

Comment 12

[Mike Kaply [:mkaply]]

Yeah, that policy change didn't need to be in the patch. I'll open a new bug.

Could you please post link to the new bug?
