The only thing I would add is that while Mozilla is implementing most of the API that Chrome and Opera support, weвЂ™re not restricting ourselves to only that API. The API is also fully compatible with multiprocess Firefox. Well, it works, but itвЂ™s not really pretty. Extensions written for these browsers will in most cases run in Firefox with just a few changes. Make sure it looks like this, rebuild, re-install, and shazam, it works! Making it look nice The first file weвЂ™ll need is a manifest.json, to tell Firefox about our add-on.

WeвЂ™ll add a button, and when you click it, it will open up one of my favourite sites in a new tab. Okay, letвЂ™s start with a reasonably simple add-on. But keep in mind, this is still experimental technology - things might break! Starting off Finally, since the WebExtension API is still under development, itвЂ™s probably best if you use Firefox Nightly for this tutorial, so that you get the most up-to-date, standards-compliant behaviour. Step 2: Press win + R to open the Run dialog window. Before doing so, you need to close all the active Firefox windows. Where it makes sense, we will be adding new functionality and talking with other browser makers about implementing it as well. To add Firefox extensions in Selenium using FirefoxProfile, please follow the below-mentioned steps: Step 1: Create a Firefox profile. Extensions written for these browsers will in most cases run in Firefox with just a few changes. The technology is developed for cross-browser compatibility: to a large extent the API is compatible with the extension API supported by Google Chrome and Opera. WebExtensions are a new way to write Firefox extensions. Well, IвЂ™m here to help! I think the MDNвЂ™s WebExtensions docs are a pretty great place to start: Maybe youвЂ™ve been wondering what it was about, and how you could use it.

You might have heard about MozillaвЂ™s WebExtensions, our implementation of a new browser extension API for writing multiprocess-compatible add-ons.
