Add-ons Update – 2017/10

Here’s your monthly add-ons update.


We changed the way contributions are handled on AMO. This should be simpler to maintain, and offer more payment options for developers.

The Review Queues

We recently moved to a new review model, where developers don’t have to wait for long before their add-ons are reviewed. Legacy add-ons still go through the old model, but there are only a small number of updates awaiting review now. So I’m discontinuing this section of the monthly update for now.

Compatibility Update

Firefox 57 is now on the Beta channel and will be released on November 14th. It will only accept WebExtensions add-ons. In order to ease the transition to 57, here are some changes we’re implementing on AMO.

    putting “by default” make it sound as it’s possible change it via some preference, but it isn’t, right?

      Right. There’s a preference, but it only worked on Nightly, so this something I forgot to change from past posts.

    Will this “Mozilla Add-ons Blog” disappear after Nov 14, and if it doesn’t disappear, do you anticipate making occasional posts if needed?

    1. Jorge Villalobos wrote on

      The blog will continue to exist, for sure.

    I build extensions for a living for myself and other customers. They key reason I would ever recommend Firefox, was because of the powerful features of XUL/XPCOM, otherwise, if I wanted WebExtensions, I would just use Chrome, as it is a far more popular browser with less problems.

    I can only think that you and a number of others are secretly getting paid by Google, to destroy Firefox. If not, you should be, because these changes are fantastic for Google Chrome.

    When I look at all the baloney that Firefox is pushing with this “Net Neutrality” garbage, as if making more laws is going to make the internet “freer”, it really seems like Firefox is done for, there is no reason to use it at all after Nov 14th.

    Even if I wanted to port extensions over, you have no equivalent way of doing it, it is impossible:

    From your own list of porting:

    The free market will come up with something to replace what you have gotten rid of, and the entire Firefox browser will soon be a “legacy”, taken down with the extensions it destroyed.
