CacheCannon

CacheCannon clears browser data and reloads the page in one click on the toolbar icon. No popup, no dialog, no trip through settings. Click, purge, reload, done. It's built for web developers who clear cache fifty times a day, but anyone can use it. PICK HOW HARD IT HITS - Lite: cache only. You stay logged in everywhere. - Nuke: cache, cookies, local storage, IndexedDB, service workers and form data. The default. - Full Nuke: all of the above plus saved passwords, history and downloads. DEFCON 1. - Custom: pick exactly which data types get cleared and save it as your profile. Full Nuke cannot fire by accident. You acknowledge a warning once, and even after that the icon arms on the first click and only fires if you click again within 4 seconds. Until then it just sits there with a red badge, judging you. PURGE ONE SITE OR EVERYTHING "This site only" scope clears cookies, local storage, IndexedDB and service workers for the site in your active tab and touches nothing else. Fix one broken login without logging yourself out of the entire internet. You can also limit a purge to the last hour, 24 hours or 7 days. PROTECTED SITES Put hostnames on the protected list and purges leave their cookies and site storage alone. Keep Gmail and GitHub logged in while everything else gets cleared. AFTER THE PURGE Pick what happens next: hard refresh the tab, reopen the page in a fresh tab, reopen it in an Incognito window, close the window, or send the page straight to a speed test. THE SMALL STUFF - Alt+Shift+C purges and reloads. Alt+Shift+S nukes just the current site. - Right-click the icon or any page for one-off actions. - Prefer buttons? Turn on the optional panel. It stays off by default because one click is the whole point. - Four themes: Matrix, Amber, Ice and Mono. - A green badge flash confirms each purge, and the options page keeps a purge counter. - Optional cannon sound. Off by default. You're welcome. - Export your settings to a JSON file and import them on another machine. PRIVACY, THE SHORT VERSION No tracking, no analytics, no ads, no remote code, no host permissions. Settings live in local browser storage and never leave your machine. Full policy: https://cachecannon.com/privacy.html NEW IN 2.0 Per-site purging, time ranges, custom purge profiles, protected sites, keyboard shortcuts, an optional button panel, themes, purge stats and a proper two-step guard on Full Nuke, plus a long list of 1.0 bug fixes. One heads-up: 2.0 keeps settings strictly in local storage for privacy, so your 1.0 settings may reset to defaults once. Setting them back up takes under a minute. Built by LXB Studio LLC.

What this update means for you

Layperson summary from Qwen3

Die Erweiterung wurde verbessert, um gezielter Cache und Website-Daten zu löschen und direkt Performance-Tests zu starten. Es wurden keine riskanten Berechtigungen hinzugefügt. Die Änderungen sind sicher – ein Update ist empfehlenswert, besonders für Entwickler.

CacheCannon ermöglicht es Nutzern, mit einem Klick den Browser-Cache und andere Daten zu löschen, die Seite neu zu laden oder Performance-Tests durchzuführen.

Privacy impact

Gering: keine neuen Berechtigungen für Datenzugriff, aber mehr externe Test-Tools werden aufgerufen.
