Title:
firefox extension's prefs.js does not work in ubuntu version of
firefox
Status in “firefox” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: firefox
I have created this Firefox addon for Firefox 4 some time ago:
https://addons.mozilla.org/en-us/firefox/addon/classic-opera/
This addon has a defaults/preferences/prefs.js file that sets a few
default preferences:
pref("browser.tabs.closeWindowWithLastTab", false);
pref("browser.tabs.insertRelatedAfterCurrent", false);
pref("browser.tabs.warnOnClose", false);
After upgrading to Natty, i switched from the FF i downloaded from
mozilla.com to the one provided by Ubuntu.
Suddenly the preferences from prefs.js weren't being set anymore. I
disabled all the other addons - this did not make a difference.
Then i switched back to the mozilla.com version of Firefox and the
prefs.js settings were working again.
Switched to Ubuntu FF again and the problem was back.
In an effort to fix the problem in the addon's code, i went to my
~/.mozilla/firefox/<blah>.default/extensions/ directory and unpacked
the contents of the classic-op...@oele.net.xpi archive into it's own
directory so that i could edit the scripts. (so i replaced the file
classic-op...@oele.net.xpi with the directory classic-op...@oele.net
with the same contents)
When i restarted Ubuntu Firefox, suddenly the prefs.js settings were
being set correctly! Restarted FF various times, and it kept on
working. Then i re-packed the addon in an XPI file and it stopped
working again.
So, it seems that for some reason Ubuntu Firefox ignores the prefs.js
file of .xpi packed extensions, but not of unpacked extensions?
To reproduce the problem:
- install Ubuntu's Firefox 4
- download Mozilla.com's Firefox 4 and extract it somewhere on the
hard drive
- install the classic opera plugin in one of the browsers (they share
one profile directory, so you'll only have to do this once)
- go to about:config and look at browser.tabs.closeWindowWithLastTab,
browser.tabs.insertRelatedAfterCurrent and browser.tabs.warnOnClose .
Compare these settings in both versions of the browser.
- exit Firefox and go to
~/.mozilla/firefox/<something>.default/extensions/ and unzip the
extension into it's own directory: unzip -d classic-op...@oele.net
classic-op...@oele.net.xpi && rm classic-op...@oele.net.xpi
- look at the same settings again in both versions of FF.
