803486 - Override compatibility for Signature Switch add-on on Thunderbird

Status: RESOLVED INCOMPLETE

(Firefox :: Extension Compatibility, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Thunderbird 16.0.1, Windows XP SP3 32 bit

Add-ons incompatible with the version you upgrade to are not disabled.

Steps to reproduce:
1. Get Thunderbird 12 and install it.
2. Install the Signature Switch add-on from the Add-ons Manager search (on AMO: https://addons.mozilla.org/thunderbird/addon/signature-switch/ )
3. Restart Thunderbird to complete installation.
4. Quit Thunderbird
5. Launch that profile with Thunderbird 16.0.1

Actual result:
Signature Switch is still active despite incompatible maxVersion in install.rdf (7.*) and on addons.mozilla.org (12.*)

The update.rdfs from addons.mozilla.org list 12.* as maxVersion:

https://versioncheck.addons.mozilla.org/update/VersionCheck.php?reqVersion=2&id={2ab1b709-ba03-4361-abf9-c50b964ff75d}&version=1.6.9&maxAppVersion=12.*&status=userEnabled&appID={3550f703-e582-4d05-9a08-453d09bdfdc6}&appVersion=16.0.1&appOS=WINNT&appABI=x86-msvc&locale=en-US&currentAppVersion=16.0.1&updateType=97&compatMode=normal

The issue doesn't occur with Firefox if I install https://addons.mozilla.org/firefox/addon/screen-capture-elite/ into and eventually upgrade to Firefox 16.0.1: The add-on gets disabled.

This bug is problematic due to outdated extensions breaking application UI / code.

<jorgev> Archaeopteryx: warning about compatibility problems doesn't disable Default to Compatible in any way
<jorgev> if we determine that an add-on is causing problems or completely broken on a new Firefox version, we can add it to a compatibility override list that does declare de add-on as incompatible

Ok, so please block the Signature Switch add-on, people get confused because it exposes its UI, but is broken if a user replies to an email. (Source in German: http://www.thunderbird-mail.de/forum/viewtopic.php?f=10&t=60206 )
