From the beautiful and most fascinating CNET Special Report on the Mozilla Firefox rebirth:
But another change in Firefox 57 will break a venerable part of Firefox — the extensions technology that lets you customize the browser. For example, with extensions you can block ads, protect your privacy, download YouTube videos, translate websites and manage passwords. Extensions were a key advantage back when Mozilla first took on IE in 2004, but Mozilla is switching to Web Extensions, a variation of Chrome’s customization technology.
I found that the only reason that keeps me far away to Firefox is the poverty of their universe of extensions. Some are obsoleting, some with missing features and much others absent (comparing with Chrome, obviously). And it’s an absurd because Mozilla was the first browser with a large add-ons store.
Next big Firefox version it will provide the simplest way for developers to build extensions and convert a Chrome Extension to a Web Extension. It could be a comeback revolution and would be meaning a huge exodus to the Mozilla’s browser for all users, like me, that has lived a web diaspora.
Good news on the open side of the web.
