Simple = Select + Search di Diego Presno

After multiple requests, here's a port of this extension to Firefox.

Select some text. Right-click. Search it — on the engine you actually wanted.

If a site has a search box, it can live in your right-click menu: run a search on it, copy the address, and swap your term for %s. Or skip the fiddling — the built-in catalogue has 100+ ready-made engines to add in a click.

What else it does

• Search Everywhere — one selection, every engine in your set, one tab each.
• Folders — group your engines, nest them up to five deep.
• Sets — separate collections like Work, Personal and Research, switchable from the toolbar.
• Drag-and-drop reordering, and your rules: new tab or new window, private window per engine.

What's new in v3 — a complete, ground-up rewrite: nested folders (asked for since 2014), multiple sets, the catalogue, and a migration that brings your old engines across automatically — keeping your old settings as a backup it never deletes.

Free, since 2011. Everything above is free, and stays free. Pro comes later, in v3.1, for the pieces that need real upkeep.

About your data: the text you select never reaches us — it goes to the engine you picked, by ordinary navigation. The extension counts usage pseudonymously in Google Analytics; the text you search is never in there. Full detail in plain language: https://simpleselectsearch.com/privacy

I built this in 2011 with a baby in one arm. It's still mostly me, nights and weekends. Thank you for using it.
