Last year, Mozilla has revealed that it aimed to ultimately need all the plugins to be ‘Click to Play’ by default, which means that the users will have to tap on their desired plugins in-page to activate them as well as view their content. And today, the company has finally announced that it will put an end to the application window for whitelisted plugins on 31st March, however, it will only start blocking by default no sooner than Firefox Browser 30.


This new click to play feature blocks the implementation of plugins automatically so that the sites will not be able to load contents that utilizes browser plugins. Moreover, users have will have the ability to keep the block in place, activate a plugin on a particular site for the time being, or even enable it permanently on the site.

Plugin developers are allowed to submit an application to join a plugin whitelist. But the application should send before March 31, 2014 and the company reviews the applications if they are sent before the due date.

If joining in the whitelist is approved, the plugin in question will be provided a whitelist status which means that it is excluded for a 30 weeks grace period. Developers can then request for another one, and if it is also approved, their plugins are exempt for the next 24 weeks.

The company has highlighted that the plugin whitelist is just temporary and it will whitelist one plugin for 4 successive Firefox launches. After that, the developers are encouraged to switch to the Web-based technologies or will have to apply for a continued freedom.

Whereas, some of the plugins like Adobe Flash, will be able to exempt permanently from this new click to play option, however it’s only for the most recent version of the player. While the former versions will turn back to requiring users in order to click to play or will need them to revamp the plugin.

The company has unleashed the revamp on the Mozilla Security blog. The director of product management at the organization has revealed that Firefox would start blocking plugins by default as soon as possible.

This update is a great one as some of the plugins are harmful for the browser performance as well as stability, so aiming them to disable by default that should bring a more stable browsing experience to users.
