Extra Volume Booster. Increase sound

On installation, the extension silently opens a new browser tab pointing to 'https://extravolume.net/api/install', sending an HTTP request to the developer's remote server. This request automatically exposes the user's IP address, browser fingerprint (User-Agent, Accept-Language, etc.), and can be used to build a persistent install database for tracking. While opening an install page is common, combining it with `<all_urls>` host permissions and `tabCapture` creates a privacy concern because install telemetry is sent without user consent or disclosure.

Background.install = function() {  chrome.runtime.onInstalled.addListener((function(e) {    "install" == e.reason ? chrome.tabs.create({      url: "https://extravolume.net/api/install"    }) : e.reason  }))}, chrome.runtime.setUninstallURL("https://extravolume.net/uninstall/");

When the volume booster is activated, the extension stores the full URL of the active tab (`e.url`) into `chrome.storage.local`. A volume booster has no functional need for the tab's URL — only the tab ID is required for audio capture via `tabCapture`. Persisting the browsing URL in extension storage constitutes unauthorized data collection of browsing history, and this data is available to all extension scripts.

Power.visualOn = async function(e) {  await Methods.save({    id: e.id  }), await Methods.save({    url: e.url  }), await Methods.save({    power: !0  }), $("#power").attr("class", "on"), Methods.setIcon("on"), Popup.showModules(), Popup.advancedInit(), Mono.init(), Phased.init(), Popup.setTitle(await Methods.load("id")), Tabs.tabInit()}

The extension registers an uninstall tracking URL with the Chrome runtime. When the extension is removed, Chrome automatically navigates to this URL, allowing the developer's server to log the uninstall event along with associated identifying data (IP address, User-Agent). This is an undisclosed tracking mechanism that fires without user interaction or consent at uninstall time.
