Page Tinker by HalfToast

Edit, hide, delete, screenshot, or find-and-replace anything on a web page, just click it. No DevTools, no digging through the HTML inspector.

Page Tinker puts a small floating toolbar on the page so you can:

• Edit text in any element - fix a typo, mock up a change, tidy a page before sharing
• Hide or Delete elements - declutter a page or clean it up for a screenshot
• Screenshot a single element straight to a PNG
• Find & replace text across the whole page, with matches highlighted live as you type
• Undo / redo every change (Ctrl+Z / Ctrl+Shift+Z)

Drag the toolbar out of the way whenever it covers what you need. Every change is temporary, reload the page and it's exactly as it was. Nothing is ever saved.

Privacy first: no host permissions, no storage, no network requests, no telemetry. Page Tinker only touches a page after you explicitly start it (toolbar button, right‑click, or Alt+Shift+E), and only that one tab. Works on Firefox for desktop and Android.
