Filter Rules sorting - fails if no quickFilters Pro license

[RealRaven2000]

When clicking "Sort" in Filter editor this only sorts the search terms if a valid pro license is present. There is also a message

Expected behavior: the message shows but the sorting feature works anyway.

Error log:

quickFilters 10:23:42.837 [21072 ms]

My guess is that it relies on saved "countdown" settings that are not generated in a fresh profile. The countdown feature was an attempt to convert some of the users to license buyers because people don't rally react to the Premium Feature notification. With custom templates you could generate a bunch, ignore the warning and then use them forever (even if you were blocked from creating more).

I did some tests and fixed some problems with missing strings, but it turns out you cannot use sort filters without pro license at all. it's probably one of the reasons I actually sell licenses, so I don't want to change this behavior. However I need to change the notification text which reads:

{1} is a Premium feature, please get a quickFilters Pro License for using it permanently.

This is a generic error message that use for other features that have a "countdown" of uses, but here I need to drop "permanently". For full transparency, I should add - "You can use this feature N more times..."

The old countDown code is actually broken. it doesn't assign the countDown from the default, resulting in the value to be set to -1 immediately:

  if (notifyBox) {
    let notificationKey = "quickfilters-proFeature",
        countDown = null;
    try {
      if (featureName.indexOf('Advanced search') == 0)
        featureName="advancedSearchType";
      prefs.getIntPref("proNotify." + featureName + ".countDown") ; 
      if (notifyBox.getNotificationWithValue(notificationKey)) {
        // notification is already shown on screen.
        util.logDebug('notifyBox for [' + notificationKey + '] is already displayed, no action necessary.\n'
                                   + 'Countdown is ' + countDown);
        return;
      }
      countDown--;
      prefs.setIntPref("proNotify." + featureName + ".countDown", countDown);
      util.logDebug('Showing notifyBox for [' + notificationKey + ']...\n'
                                 + 'Countdown is ' + countDown);
    }

Here is a version with a more transparent (to be localized) message and a "real" new countdown for premium features:

quickFilters-wx-5.4.1pre51.zip

to install this prerelease, download the zip file and drag into Thunderbird Add-ons Manager (without extracting)

The message will be displayed per feature, looking like this:

Fixed in 5.5 - released today
