Apple, Google, Microsoft and Mozilla team up for a 'common vision' on extensions

The major browser makers — Apple, Google, Microsoft and Mozilla — are working together "to advance a common browser extension platform." This newly formed WebExtensions Community Group explained what it doesn't plan to do, "plan to specify, standardize or coordinate around extension signing or delivery," while still making it easier for developers to write the tools with a "common core of functionality, APIs, and permissions."
