Explanation of Permissions

###Permission (as shown by the web browser) #####Read and change all your data on the websites you visit This is caused by the <all_urls> permission in the manifest.json file. The extension does not modify the page, except create hooks to media in JavaScript and modify HTMLMediaElement.

#####Read your browsing history This extension does not have access to your browsing history. This message is most likely caused by the <all_urls> or webNavigation permission declared in the manifest.json file. Both of these permissions give me indrect access to the a tab's URL. I use the URL from webNavigation only for [Mode Rules](Modes and Mode Rules).

###Permissions declared in the manifest.json file #####webNavigation Used for the following:

• Detect when a tab navigates to a new page, so the extension can set the correct [Mode](Modes and Mode Rules) for the page.
• Run content scripts on the page, which disables autoplaying on the page. Content scripts are not run if the Mode is set to disable nothing.

#####<all_urls> Used to run content scripts via chrome.tabs.executeScript. Content scripts are what disable autoplaying.

#####storage Used to have access to the local storage, so your options can be saved.

#####unlimitedStorage Used to have unlimited local storage to prevent a length restriction on Mode Rules List.

###Background script #####"persistent": true Used so the extension can keep track of the tab states and Mode settings.
