WebExtensions and code review

All add-on files listed on addons.mozilla.org (AMO for short) have undergone code review and testing by a team of volunteer and hired add-on reviewers. The review team’s goal is to ensure these add-ons do what they claim to do and are safe to use. Most safety issues come from add-on code that unintentionally puts users […]

Using WebExtensions to communicate between iframes

After my presentation at FOSDEM, I was approached by developers who had a specific use case for an add-on. They asked which of our add-on technologies they should use to implement it, and whether it was practical to do. I knew it was doable, and I thought it would be an interesting programming exercise, so […]

Some notes on WebExtensions discovery

As I was preparing for my presentation at FOSDEM, I tried to approach WebExtensions from a beginner’s perspective and document the entire process. I wrote it all down on this Etherpad, if you’re interested in the raw notes. This blog post is about the first part of the notes: discovery. We have a history with […]

WebExtensions presentation at FOSDEM 2016

Last week, a big group of Mozillians converged in Brussels, Belgium for FOSDEM 2016. FOSDEM is a huge free and open source event, with thousands of attendees. Mozilla had a stand and a “dev room” for a day, which is a room dedicated to Mozilla presentations. This year I attended for the first time, and […]

Extending the New Developer Toolbar

Firefox 16 will be released in a couple of days. Among its many improvements, there’s the new Developer Toolbar. This toolbar is essentially a command line that allows you to execute commands on the developer tools, like inspecting elements, starting up the debugger and generating screenshots from web content. This feature is designed to be […]

Should we fix Personas?

This post is about Personas, also known as lightweight themes, not Browser ID, now known as Persona (naming is fun!). Also, these are just my thoughts, not an official position of Mozilla or the Add-ons Team. I think we skipped a step when we graduated Personas from Mozilla Labs and implemented them as a Firefox […]

Running multiple Firefox instances on Mac OS

I visit my Google Plus Stream every now and then to see if there’s anything useful in it. Unsurprisingly, most of the time there isn’t anything. I blame primitive filtering and lack of users. But one thing that caught my eye was a post by sheppy, asking about running multiple versions of Firefox easily. While […]

Firefox 4 for Add-on Developers For now, this is a pretty good reference if you want to start supporting the Firefox 4 betas in your add-ons. I’ll be […]

XPI v2 – Making Extension Development Easier

Note: this is just me throwing some ideas around. It is not an official proposal or spec. Having said that, I would like everyone that has interest in extension development to read this post and tell me what they think. I’ve been an extension developer for a long time, and I like to think that […]

And now they wait…

I guess giving 3 month’s advanced notice wasn’t enough for most add-on authors. I guess this is partly our fault, and we should stress enough how important it is for them to stay up to date with Firefox new, or at least the Add-ons Blog. On Thursday, the update queue had about 80 add-on updates […]
