About

Style Probe lets you hover any element on a normal http(s) page to see computed CSS, then click to copy it. Chrome://, the Web Store, and other restricted pages are skipped. Free tools stay in this browser — no ExtHub account. Turn Inspect on in the popup, pick Pretty, Compact, or Selector, then click an element. Shift+click copies all properties; Alt+click copies the selector. The tooltip shows box size and a color swatch. Esc exits. Last copies stay in the popup (filter, click a row to copy again, copy-all). Up to 50 locally. Pro can sync that copy log to ExtHub and restore it in the popup. Search and CSV/JSON export are on ExtHub. Page HTML is never uploaded.
