The Mozilla Firefox is used by about 30% of all Internet users, and the company has been seriously concerned about user security for many years.
To improve the stability, security, and performance of Firefox, Mozilla announced in 2013 that it planned to enable the "Click to Play" option in upcoming versions of Firefox, which would block the most vulnerable plugins like Java by default.
«Plugins are a significant source of poor performance, malfunction and vulnerable points», said a Mozilla spokesperson.
The feature «Click to play» prevents the automatic execution of all plugins, although this feature was annoying for some users, so that there is no default lock for each plugin, Mozilla announced that it will maintain a list of approved plugins.
Developers of plugins can submit a request for their application to be included in the list of allowed ones. The developer must submit their plugins using a template in Bugzilla and the request is submitted by March 31, 2014, when it will be reviewed by Mozilla.
The most widely used web browser, Google Chrome, is also moving in this direction and last January blocked all NPAPI plugins except for Silverlight, Unity, Google Earth and Facebook Video.
