Firefox auto update prompt


Firefox is becoming more aggressive with their “Download a fresh copy of Firefox”, which in previous releases you could set the boolean value “ = false” and suppress the update prompt. We are no longer able to do this and Firefox wants user to use the group policy file to make these changes now.

The issue I have run into is that the policy file lives within the snap directory “/snap/firefox/current/distribution”. Is there a solution for this or would it be as simple as creating a symlink directory to my home snap folder and setting the policy file there.

Future Maintaining Thunderbird

IMO this should be done by the snap publisher(Mozilla), contact them to set the policy.

#3 doesn’t suppress the update check, it simply commands firefox to not install automatically available updates, effectively resulting in a prompt.

As you stated, the recommended way of disabling update checks is a group policy indeed.

And as suggested by @Lin-Buo-Ren, this should be done by the snap publisher themselves.

Bug #1436457 is related.


I experimented with adding a policies.json file under distribution in a repacked firefox snap, with the following content:

  "policies": {
    "DisableAppUpdate": true

This disables updates, as expected. However, the about dialog has the following message, which might look scary to non-tech savvy users:

Updates disabled by your system administrator

This is still an improvement over the current situation, so I’m going to submit this upstream to see if the approach is acceptable.
