433844 - Can install add-ons into RC1 whose maxversion is 3.0b5pre

Status: VERIFIED DUPLICATE of bug 433371

(Toolkit :: Add-ons Manager, defect)

Description

[Marco Zehe (:MarcoZ)]

When testing the accessibility for Add-Ons Manager on both Windows and Linux, I found that I could install add-ons into the Windows version of 3.0RC1 that I could not install into the Linux version.

STR:
1. On Linux, open Firefox 3 RC1.
2. Go to Tools/Add-Ons.
3. On the Get Add-Ons page, look in the list of recommended add-ons. I'm seeing ScribeFire, Download Statusbar, and FoxyProxy.
4. Right-Click Download Statusbar and choose "Add to Firefox".
5. After the countdown, click "Install now".

Result: Add-On will not be installed, complains that it is not compatible with Firefox 3.0.

6. Repeat Steps 1 through 5 on Windows.

Expected: Same result.
Actual: The add-on installs fine, Firefox prompts you to restart, and after the restart, the add-on is available.

7. Open the URL given above, and download the XPI by right-clicking "Add to Firefox".
8. Look in the XPI. The install.rdf file shows the max version being 3.0b5pre!


Additionally, I am also seeing that Adblock Plus, ScribeFire, IETab are also active in my 3.0RC1 installation. I cannot install any of these in Linux with the same "Incompatible version" error message, yet they are active on Windows.

All of those add-ons should install correctly on Firefox 3 so this would be a fault with the Linux version not detecting the compatibility information correctly.

Dave, I don't really think so. As Marco told me on IRC it also happens when installing such an add-on locally. Having a look inside the install.rdf shows me following:

<!-- Target Application this extension can install into, 
        with minimum and maximum supported versions. --> 
    <em:targetApplication>
      <Description>
        <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
        <em:minVersion>2.0</em:minVersion>
        <em:maxVersion>3.0b5pre</em:maxVersion>
      </Description>
    </em:targetApplication>

So this add-on shouldn't be compatible with Firefox 3 RC1, right? In that case no installation should be possible.

My Linux is an ubuntu 8.04, and as mossop asked, I did run the Ubuntu version of Firefox once before I ran RC1. I used that version to download RC1 as a matter of fact.

When an add-on appears to be incompatible we request updated compatibility information from AMO. In the case of all the add-ons listed in this bug AMO is saying they are compatible with 3.0.*.

From talking on IRC I am pretty confident that this is due to bug 433371. Marco's profile showed signs of Ubuntu's language packs which shouldn't have been there and after recreating the extensions datasources installation succeeded.
