Addons make the difference between a regular web browser and a browser that just got “pimped” (you can also pimp your email client, too ). Having a wide variety of extensions and themes helps developers and product managers focus on core features the majority of users will need without having to simply say, “sorry, nope, can’t do that”.
Okay, so maybe your average extension isn’t going to turn your world upside-down the way West Coast Customs spending a week with your Honda would… fine. But addons for and by the people are a vital and important bridge between a non-bloated application core and end users who want personalized functionality.
Once we understand the importance of addons, and the role addons.mozilla.org (AMO) plays for Mozilla products, we can start to focus on improving it.
So it’s great to see healthly discussions about the future of the service, and how it should be modified to ensure we ship addons with a level of quality that is comparable with Firefox or Thunderbird.
I recently read David Baron‘s excellent post about the danger of extensions and how an undersupported and relatively unregulated addon service could mean disaster for Mozilla products and Mozilla’s reputation in the community.
To say the least, I am now filled with uncertainty and doubt.
Though it’s not about the service itself, or whether or not the community will be able to recover from the first security hole found in an extension, or how extensions are external to the normal Mozilla review standards.
I’ve got FUD about how these products will thrive if they cannot change and adapt themselves quickly to new trends, web services or client-side tools that are available in other browsers.
Despite the theoretical holes in AMO, it’s there, it’s important and it’s popular — for better or worse. It has many great extensions, some good ones, and many poor extensions as well. It’s a distribution as diverse as the community; filled with the good, bad, and the ugly.
And the dangerous? Maybe. David’s points are valid — I share his concerns as well — but assuming problems with extensions will translate into plumetting consumer confidence in an application isn’t necessarily such a straight line. The risks we take with AMO would also need to be compared with consumer confidence in a product that didn’t adapt and offer unique features not found anywhere else.
It’s clear — we’ll have to find the solution halfway. We need to improve the overall quality of addons by improving the review process, and making moves to encourage the same openness and exposure Firefox and Thunderbird get. Most of these changes start with an improved (and solidified) policy, which is currently a major focus.
The technical solution could be CVS integration, stricter review requirements, Bugzilla integration. Ideally, we would have all of those, and everybody would develop, test and verify quality for their own extensions the way Mozilla does for Firefox and Thunderbird.
That all sounds great. Now, who’s going to do it? What would the practical schedule be for a new addon? A new extension version? When does the process of controlling the processes become simply overwhelming?
While I wish it were, I have to say the complete Mozilla review process isn’t a perfect fit for addons. It would delay addon releases, create a barrier between developers and the community, and create a lot of additional work for addon developers — who would most likely be satisfied with keeping their extension simply on their own site, in their own repository, with their own bug reporting software.
So how do we properly review this stuff, then? Myk Melez brought up some good ideas about a modified rating system to guage the overall “trustability” of a given extension. I thought that his approach would be a good one given the unique nature of the addon life cycle:
(Our current system) has a number of problems:
- it ignores other trust metrics that would refine our sense of each extension’s trustworthiness;
- there have never been enough reviewers, so extensions often wait days or weeks to get reviewed;
- generally only one reviewer reviews each extension, increasing the risk of human error;
- reviewers review extensions they aren’t personally interested in, so they exercise them less thoroughly than the ordinary users they approve them for;
- there’s little reward to being a reviewer, and the downside (being held responsible for approving a harmful extension) is significant.
An alternative approach is to publish each extension to the site the moment it is submitted but hide it from the majority of users until it reaches a trustworthiness threshold which takes into account all available trust metrics, including user feedback, code review, whether it is open-source, whether it is signed with a valid code-signing certificate, the trust score for other extensions by the same author, etc.
Until then, only specially designated “tester” users who have been apprised of the dangers and are willing to face them can access the extension. These testers, a much larger group than the current pool of reviewers, will provide feedback on such extensions like ordinary users, and that feedback will serve as one of the trust metrics through which an extension can reach the trustworthiness threshold required to make it available to the rest of the users.
This approach has several benefits over the current approach:
- testers try out extensions they’re interested in using, so they exercise them more thoroughly;
- multiple testers must look at and provide generally positive feedback for each extension before it satisfies its “user feedback” metric, so no one tester is solely responsible for deciding if an extension is good;
- each extension’s trust score comprises multiple trust metrics, increasing the quality of our decisions about each extension’s trustworthiness.
And, I strongly suspect, the mean time to publication will decrease significantly.
Myk’s idea is basically to properly weight the different metrics unique to the AMO process to determine whether or not an extension is trustworthy. It’s like an improved Digg mentality with a bit of moderation. While there is definitely more discussion needed in the next month, this would be a great place to start.
Sometimes pushing the envelope can give you a paper cut.
