Bleep - Fast Global & Tab Cache Cleaner

A browser extension for clearing cache, cookies, storage, history, and other browsing data — either globally across every site, or scoped to just the one open tab you're looking at.

Features

• Granular data types: Cache Storage, HTTP Cache, IndexedDB, Local Storage, Session Storage, Cookies, Service Workers, History, Download History, Form Data — pick exactly what to clear.
• Two scopes:
  • Global — clears the checked types across every site you've visited.
  • Per site / domain — clears data for one open tab only, leaving every other site untouched.
• Quick actions in the popup — clear the active tab or everything with one click, without opening the full Settings page.
• Full control in Settings — the complete type list, a searchable/ filterable list of open tabs for per-site clearing, bulk "clear all open tabs" action, and a recent-history browser with per-item delete.
• Two-step confirmation on the destructive "clear all sites" action — arms on first click, only fires on an explicit second click, auto-cancels after a few seconds if ignored.
• Theme: System / Light / Dark, following the OS by default.
• Language: Auto-detected from the browser (English, Russian, Romanian, Ukrainian), with a manual override — falls back to English for any other browser language.
• Reset to defaults button to restore all settings in one click.

How it works

Global clearing

Uses the browser's browsingData API directly. No extra permission is needed beyond what's declared in the manifest.

Per-site clearing

There's no single cross-browser API for "clear this one site's data":

• Chromium (Chrome, Edge, Brave, ...) — browsingData.remove accepts an origins filter, so per-site clearing goes straight through that API.
• Firefox and Firefox-based browsers (Zen, LibreWolf, ...) — Firefox's browsingData has no per-origin filter at all. Instead, the extension injects a small content script into the target tab and clears caches, indexedDB, localStorage/sessionStorage, cookies, and Service Worker registrations directly from the page's own context. This only reaches the non-HttpOnly cookies for the tab's current path/domain, and only works on tabs that are actually open (a backgrounded or discarded tab can't be injected into).

Which browser you're on is detected via runtime.getBrowserInfo — a Gecko-only API present in Firefox and its forks, absent in Chromium. Its presence (not the self-reported name, which forks often report as "Firefox" for compatibility) is what selects the code path.

Per-site clearing always asks for a one-time, optional host permission on first use — *://*/*, declared as optional_host_permissions rather than a required permission, so it's not requested at install time.

Supported browsers

Browser	Minimum version	Notes

Firefox	128+	optional_host_permissions support; per-site clearing via content-script injection
Firefox-based forks (Zen, LibreWolf, Waterfox, ...)	Same as Firefox	Detected via runtime.getBrowserInfo
