Mozilla announced on Friday that will now support Chrome plugins with WebExtensions API instead of Firefox add-ons. That way it will be easier for developers to deploy Chrome extensions to its browser and to maintain the safety and stability of the browser.
“We would like add-on development to be more like Web development: the same code should run in multiple browsers according to behavior set by standards, with comprehensive documentation available from multiple vendors,” Mozilla said in a blog post.
“We currently use a blocklisting mechanism to defend against malicious add-ons, but additional measures are needed to better protect our users as some add-on developers have adapted to work around blocklisting” said Mozilla.
However, the company is conscious about possible trade-offs. While developers who already support Chrome will have it easier since they will have one codebase to support instead of two, developers of Firefox-only add-ons will have to make some considerable changes.
