about:config "show release notes" = false setting is ignored

[nodiscc]

Hello,

I have placed Decentraleyes' XPI package at /usr/share/firefox-esr/distribution/extensions/[email protected] for automatic installation in new profiles (Debian 9 Stretch), along with other addons.

In /etc/firefox-esr/firefox-esr.js [1] I have set pref("[email protected]", false); to prevent Decentraleyes release notes from showing up on Firefox startup each time a new profile is created.

However when I run a Firefox profile for the first time, the release notes are displayed.

Looking through about:config I see that [email protected] has been reset to true. In ~/.mozilla/firefox/xxxxxx.default/browser-extension-data/jid1-BoFifL9Vbdl2zQ@jetpack/storage.js there is also a setting reflecting the about:config value (eshowReleaseNotes":true).

Somehow Decentraleyes seems to reset that setting to true when a new profile is first launched. How can I prevent this?

Thanks

Hi @nodiscc, and thanks for getting in touch. It seems that your current approach results in the creation of a configuration entry of type default. Entries of type user set are typically a lot more resilient.

For that reason, I would personally suggest following the steps outlined in Customizing Firefox Using AutoConfig (a guide by Mozilla). Following the instructions, should result in the creation of a configuration entry of the desired type (user set). Decentraleyes does not modify such entries on installation.

Basic AutoConfig Example

$FIREFOX_INSTALLATION_DIRECTORY/defaults/pref/autoconfig.js

pref("general.config.obscure_value", 0);
pref("general.config.filename", "mozilla.cfg");

$FIREFOX_INSTALLATION_DIRECTORY/mozilla.cfg

// IMPORTANT: Start your code on the second line.
pref("[email protected]", false);

Please do let me know if the suggestions above helped to solve your issue.
