// Plugins Permissions button for Custom Buttons
// (code for "initialization" section)

// (c) Infocatcher 2012-2020
// version 0.1.2pre3 - 2020-02-12

// Based on Cookies Permissions button
// https://github.com/Infocatcher/Custom_Buttons/tree/master/Cookies_Permissions

// Note: plugins.click_to_play in about:config ("Block plugins" checkbox) should be enabled
// Unfortunately since Firefox 20 (Gecko 20) global exclusions doesn't work, only on per-plugin basis.
// So you should change "Flash", "Shockwave Flash" and "plugin:flash" in the source (and create copy
// of this button) to menage other plugins, see "// Rename to use button for another plugin" comments.
