There's no way to change the search engines. There are no options whatsoever. Absolute garbage.

找了好久的划词搜索，很好用

All I needed, works perfectly.

Exactly what I needed.

It works! Which is most important.

firefoxに標準でついていても違和感がないほどによくできています。私はこのようなものを求めていたので非常に助かりました！

It's very good, but if i disable some search engine from Firefox option, they are always visible. The only way is to delete them. Thank you so much.

Does just what it says. All your default Firefox Search Engines presented cleanly in the context menu. You can't add search engines independent of the Firefox browser (for that you'll want Swift Search Selection), but if all you want is what's already in your address bar then this is perfection. No unnecessary permissions, no unnecessary features, what you see is what you get. Pair it with the "Add custom search engine" add-on and you have a match made in heaven.

Edit: From five to four stars because there's no way to disable the search engine shortcuts, which in turn affects how engines are displayed in the context menu.

fire gesture之后，找了好久的划词搜索，终于找到了

Does exactly what it says on the tin and does it well. It picks up your existing Firefox search engines, so you only need to maintain one list. All other similar context menu search tools I had tested required a second list to be added. The only small hassle is that Firefox doesn't allow adding custom search engines out of the box (as far as I know), so I would also recommend another wonderful add-on that is the perfect companion to Simple Context Search: Tom Schuster's Add Custom Search Engine (https://addons.mozilla.org/en-US/firefox/addon/add-custom-search-engine/). These two add-ons working together will significantly enhance your web-browsing experience.

Does the same thing as other extensions, but without any permissions needed. Perfect.

大神，请问有没有火狐五六版能用的扩展？非常喜欢这个功能！

Does exactly what it says, without any extras.

Please add an option to open searches in background without holding down the "ctrl" key.

Do exactly what I need.

very good work, I hope there will be further updates
