QuickLookup от Sqmon

Firefox already lets you right-click selected text to search — but it's slow, limited, and locked to a short list of search engines you didn't choose. QuickLookup fixes that.
Highlight any text on any page, press your custom keybind, and instantly search it on whatever search engine you actually use. Google, DuckDuckGo, Perplexity, Wikipedia, a developer docs site, a dictionary, a niche database — if it has a URL, QuickLookup can search it.
Why QuickLookup?

One keypress, zero friction. No right-clicking, no menus, no interrupting your flow.
Any search engine. You're not locked into Mozilla's default list. Add any URL-based search engine you want.
Fully customizable keybind. Set the shortcut that feels natural to you.
Built for power users. Researchers, students, developers, writers — anyone who lives in the browser and looks things up constantly.

Stop letting your browser slow you down. Search smarter with QuickLookup.
