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.

It's perfect. It does exactly what I need it to do. It lets me access the search engines I selected in the Firefox settings by right-clicking on selected test. There's no irritating setup required, and the selected text is forwarded to one of the engines you're already using.

I switched from this to SSS because there was always a delay from when you right click selected text to when the context menu option to search appears. Works as advertised otherwise, but I would love an update that fixed this. Seeing as it hasn't been updated since 2019, I somehow don't see that happening.

Edit: Found an extension as simple as this, but without the delay: https://cup.aihedy.com/en-US/firefox/addon/simple-context-search/

I've just installed this as a replacement for "ContextSearch web-ext", which has fallen victim to a bad case of feeping creaturism™. Compared to that Context Web Search is minimalism at its best (apart from wrapping each search engine name in "Search [foo] for [bar]", which I find quite unnecessary).

I hope this extension will keep its context menu up-to-date and tidy over time as I add/remove/re-order my search plugins. We'll see. For the time being: kudos to the author for doing one thing and doing it well!
