(Remember: you may also need to do this to allow for differences in API support between versions of the same browser.) Instead, where there are differences among the APIs, you should either offer alternative implementations or fallback functionality. In practice, this approach is likely to be too restrictive for most extensions. Handling API differencesĪ simple approach to addressing API differences is to limit the functions used in your extension to functions that offer the same functionality across your range of targeted browsers. Browser compatibility information is also included with each function and its methods, types, and events in the Mozilla Developer Network JavaScript APIs reference pages.

  • Proprietary functions, supporting browser-specific features.įor example, at the time of writing, containers was a Firefox-specific feature supported by the contextualIdentities function.ĭetails about the support for the extension APIs among the main browsers and Firefox for Android and Safari on iOS can be found on the Mozilla Developer Network Browser support for JavaScript APIs page.
  • Variations in the support for features within a function.įor example, at the time of writing, Firefox doesn't support the notification function method notifications.onButtonClicked, while Firefox is the only browser that supports notifications.onShown.
  • Lack of support for an entire function.įor example, at the time of writing, Edge didn't support the browserSettings function.

    The differences in the API functions offered in each of the main browsers fall into three broad categories:

    So, for example, this manifest.json code makes the polyfill available to background scripts:

  • The executeScript call in dynamically-injected content scripts loaded by tabs.executeScript, where it hasn't been loaded using a content_scripts declaration in manifest.json.
  • HTML documents, such as browserAction popups or tab pages.
  • manifest.json, to make it available to background and content scripts.

    To use the polyfill, install it into your development environment using npm or download it directly from GitHub releases. This polyfill addresses the API namespace and asynchronous event handling across Firefox, Chrome, Opera, and Edge. So, how do you take advantage of promises easily? The solution is to code for Firefox using promises and use the WebExtension browser API Polyfill to address Chrome, Opera, and Edge. Note: If you're unfamiliar with the differences between these two methods, take a look at Getting to know asynchronous JavaScript: Callbacks, Promises and Async/Await or the MDN Using promises page.

    This article looks at six of the main challenges faced when creating a cross-browser extension and suggests how to address these challenges. Maximizing the reach of your browser extension means developing it for at least two browsers, possibly more. However, there are differences in the API implementations and the scope of coverage among the browsers that use the extensions API (the major ones being Chrome, Edge, Firefox, Opera, and Safari). The introduction of the browser extensions API created a uniform landscape for the development of browser extensions. The major browser vendors are collaborating (with community members) to ease the development of a cross-browser extension in the W3C WebExtensions Community Group. However, work on Manifest v3 is not complete. Manifest v3 is likely to change the way cross-browser extension development is undertaken. At the time of writing (December 2021), manifest v3 is being introduced by the major browser vendors. Note: This article discusses building cross-browser extensions for manifest v2.
