Bug Description

[ Impact ]

Breaks all Voikko based spell-checking (in Ubuntu by default just Finnish, but more and more languages use the same extension) when Firefox 41 is released.

[ Test Case ]

Install Firefox 41, or alternatively use the current Firefox and check the extension warnings.

When installing a fixed package, the warning disappears in current Firefox / extension works in future Firefox. Update: it seems the future Firefox (at least from https://launchpad.net/~mozillateam/+archive/ubuntu/firefox-next/+packages) does _warn_ about the updated extension, but it does work after update.

Fixed packages for Ubuntu 15.10, 15.04, 14.04 LTS and 12.04 LTS at https://launchpad.net/~timo-jyrinki/+archive/ubuntu/voikkotest2/

To test the extension actually still works, enable spell-checking for a text area, set language to Finnish and copy-paste "tämä on testitekstia" to it. Firefox should underline the last word and offer "testitekstiä" instead (ä instead of a).

[ Regression Potential ]

Low, the extension is a simple non-compiled extension.


I have installed Mozilla Firefox 41.0a2 out of repositories, but this extension gets loaded on it too. Today this Firefox Developer Edition started complaining about the addon not being signed which prevents loading it for security reasons.

Even if this Firefox is out of repositories, when 41 becomes stable downstream Firefox is also going to suffer from this unless it has patches to disable this which would again be insecure and allow random extensions to be installed from anywhere.

Firefox Developer Edition gives "more details" which is link to <https://support.mozilla.org/fi/kb/add-on-signing-in-firefox?redirectlocale=en-US&as=u&redirectslug=add-ons-signing-firefox&utm_source=inproduct>.

Upstream has now released a 2.2 release together with signed XPI:


I tested that just building a new deb package out of the new sources (with unmodified upstream) files does not get rid of the warning, ie it does not seem to be enough that the contents match to an extension that has been signed by Mozilla. What else should be done, or am I missing something?

I think you need the signature file from Mozilla somehow.

I've tested https://launchpad.net/~timo-jyrinki/+archive/ubuntu/voikkotest2/ on 15.10 and 14.04 LTS, both seem to work fine. The "2" PPA corresponds to the bzr branches commits "Use a more proper install method and only use the signatures from the upstream xpi".

The extension seems both verified in Firefox UI and continues to work.

I tested this and it doesn't work (note that the requirement for extension signing has been pushed back another Firefox release. If you're testing with Firefox 41, then you need to enable xpinstall.signatures.required). I suspect the addonhas only had a preliminary review, which is sufficient for addons that are installed via the addon manager UI (such as those hosted on addons.mozilla.org). "Side-loaded" addons (those dropped in to Firefox by external software) require a full review in order to pass the extension signing check.

Honestly, it would be better if this addon was just hosted on addons.mozilla.org like most other addons. The only reasons it remained in the archive when we removed every other Firefox addon were that it contained a binary component and that upstream didn't provide a downloadable version of the addon. Neither of these are applicable anymore (the addon is all JS, and there is a downloadable xpi that will run on every architecture and every Ubuntu release).

The spellchecker is part of the default Ubuntu installation. Losing it from the archives would mean that 90%+ of the users would probably simply not have spell-checking, since average users are not familiar with extensions or that a spell-checking would be available from there, especially as it's not shown in Firefox's "get more dictionaries" functionality.

I don't see how it'd be better for the extension to be on AMO only other than for not needing to maintain it in Ubuntu. Unlike other extensions that were removed, this one is in main and part of the default installation - similar to ubufox.

But if AMO only is wanted, then mozvoikko should be removed from the archives for all Ubuntu versions.
