WEBEXTENSION GBROWSER ZIP
Firefox, Chrome, and Opera extensions can be uploaded in a zip format which requires the manifest.json file to be at the root of the zipped folder. Packaging of an extension in a zip format is done just for the distribution through the extensions store of the browser and is relatively straight forward. Author key will be mandatory for the user to input in Edge and optional for other browsers. While typing on Edge, it doesn’t support the command key which allows shortcut keys to be defined for extension.Įg. While typing on Firefox / Opera, it includes the developer key & information of the author name to be displayed in extension.Įg. The difference in manifest.json file is that keys are supported by browsers (Mozilla Firefox, Microsoft Edge, Google chrome, Opera) and fall into three broad categories:Įg. While typing on containers, it would be a Firefox-specific feature which supports the contextualIdentities functionality. Proprietary functionality, supporting browser-specific features.Įg. Firefox is the only browser which can support onShown. While typing on Firefox, it doesn’t support the notification functionality, onButtonClicked. Variations in the support for features within a functionality.Įg. 
While typing on Microsoft Edge, it doesn’t provide support for the privacy functionality.
Lack of support for an entire functionalityĮg. The difference in API functionalities are offered in browser (Mozilla Firefox, Microsoft Edge, Google Chrome, Opera) and fall into three broad categories: Most important thing is to ensure that the polyfill executes the earliest extension before another script except in the browser.* API namespace executes.

The executeScript call is dynamically-injected into the content scripts which can be loaded by tabs.executeScript, when it doesn’t get loaded using content_scripts declaration in manifest.json.īelow mentioned manifest.json code is implemented with the polyfill available on background scripts: (HTML and CSS files define the user interface in the browser). HTML documents, like browserAction popups or tab pages. (Manifest.json file has basic collective information of the platforms). Manifest.json, will be available for the background and content scripts.

To get access to the polyfill, install it on your machine to begin with the development of the extension using npm or you can also download it directly from GitHub releases. It simplifies asynchronous events handling.ĪPI namespace and asynchronous is addressed by the Polyfill at the time of event handling when it takes place in Firefox, Chrome, and Opera. If in any case, the promise is accepted as part of the standard followed by the system.
Firefox supports callbacks for APIs which support the chrome.* namespace. 
Callbacks can be easily accessed by Chrome, Edge, and Opera.
Promises have a standard to be followed for their extensions of API integration in Firefox. 
There are two ways for handling asynchronous events which can be accessible in among four browsers (Mozilla Firefox, Microsoft Edge, Google Chrome, Opera).
browser.* access the promises, which is modern & flexible mechanism to manage the asynchronous events. chrome.* is supported by Mozilla Firefox and also compatible with chrome to assist primarily. There are six major areas that we would be touching in this article, that will be helpful in developing cross-platform extensions:īrowser.* (Mozilla Firefox, Microsoft Edge) & chrome.* (Google chrome, Opera) are two API namespaces that are used in four browsers. There are several cross browser extensions available for Mozilla Firefox, Google Chrome, Microsoft Edge, Opera web store that are used to modify browsers and add utilities like creating notes, blocking ads, managing passwords etc. Extensions are programs that extend the browser functionality to modify the browser functionality. Internet browsers such as Mozilla Firefox, Google Chrome, Microsoft Edge, Opera gives users a simple view with a straight logic - one size that fits all.
