ContextPop by dcog989

ContextPop puts the actions you use most one click away, every time you
select text. Highlight a word, phrase, or link and a compact popup appears
with search engines and quick actions — no toolbar, no context-menu digging.

• Search anywhere — a tile grid of your search engines; add, edit, and
  reorder them, or import the engines already installed in your browser.
• Built-in actions — copy (rich or plain), copy link address, open link,
  dictionary, thesaurus, and translate, shown only for the selections they fit.
• Instant results — open in a new tab, a background tab, the current tab,
  a new window, or a popup. Shift-click opens a window; Ctrl/Cmd- or
  middle-click opens a background tab.
• Keyboard friendly — navigate with arrows, Home/End, Tab, and Escape.
• Yours to tune — light, dark, or system theme; grid columns; popup size
  and position; engine-name labels; and an accent-color border.
• On-device only — all settings stay in local extension storage; no
  accounts, no telemetry, no data collection.

Available in English, Spanish, German, French, and Hindi.
