Sillbrush: Clear Cache & Site Data

Clear cache in one click — for the current site only or for the whole browser. Sillbrush shows you which site it is about to clean and what will go before anything is removed, and afterwards it shows what really went.

Clean one site, not everything

• This site: cache, cookies, local storage, IndexedDB, service workers and Cache Storage of the page in front of you. Other sites keep you signed in.
• Include subdomains with one switch, or clean exactly this address.
• Reload the page past the cache right after cleaning, so a site that shows an old version is fresh again.

Or clear the whole browser

• Cache, cookies, site storage, history, the downloads list, form data and passwords (off by default).
• Time range: last hour, 24 hours, 7 days, 4 weeks or all time.
• Clearing cookies, history or passwords everywhere asks for a second click first.

Protected sites
Add your bank, mail and work portal once. When you clear the whole browser they keep their cookies, so you stay signed in. In some browsers this needs the optional cookie access.

See what was removed
The receipt shows real numbers: storage 40 kB → 0, service workers 1 → 0, cookies 23 → 0 (exact cookie numbers with optional cookie access). A small number on the button confirms it for two seconds. No sound.

Presets and shortcuts

• Ready presets: Site cache, Sign out here, Fresh hour, All but passwords. Rename them or make your own.
• Alt+Shift+K brushes the current site, Alt+Shift+L runs your default preset.
• Right-click the button to run any preset.
• Or let one click on the button brush the site right away.

Honest about browser limits
Some browsers do not let extensions empty the cache of a single site. There Sillbrush reloads the page past the cache instead and says so in the popup and in Help.

Works offline. Your data stays in your browser.
Presets, protected sites and the last 20 cleanings are kept only there. Sillbrush sends nothing anywhere and has no analytics.

Permissions: browsing data — to clear what you pick; active tab and scripting — to read and clean the open site only after your click or shortcut; storage — for your settings; context menu — presets on the button. Cookie access, notifications and site access are optional and asked only when you turn them on.
