While "Search selected text using your preferred search engines" does not necessarily mean the ones added in your browser, it will be understood that way by many users who will be disappointed when they see the actual functionality of the extension.
Sadly, you have to manually set yourself every single search string. If you have many search engines added, it will be a taxing endeavor.

If there was some way to export search engines and this extension could load the exported engines onto itself, then it would be worth using if you have many search engines. Otherwise it's still better to copy the text, paste it into the search bar, and then click the search engine icon in the search bar.

It is a great plugin but after the new update the settings started to reset. There is a problem in version 3.9.1. Settings are broken when you close Firefox. I installed 3.9.0 again. It works perfectly. I hope this problem will be solved with the new update.

The resetting issue was solved - this is great so it's 5 stars.

I only wish this could function like the context menu search extension for chrome which uses a key word for custom search because that allows much more customization BUT I'm pretty sure this must be a FF issue not a dev issue since no one does it like that on FF.

good，thank you

I've been using this add on for years, thank you developers! But adding it recently, my search engines keep resetting when I restart my browser, how do you stop that?

Works fine, like it should be... Thanks

Great tool. Much more powerful than you think!

坚持更新，并且越做越好。五星好评！

It did not pick up all the search engines from my search box, and automatically included several I didn't want instead.

awesome this feature should be in firefox by default

Its great., however can I suggest one feature:

Would love for a few of the searches to be directly on the right click menu rather under the Context Search drop down menu.

This one now deletes my custom search engines whenever I open the browser, but it used to work perfectly. Hopefully, there will be a fix for this soon. I appreciate all the hard work done by the developers to make a great add-on.

Super ultra mega útil .Ótimo !

A good addon providing powerful search features.

Hi Olivier. Thanks very much for this extension and your time spent developing it. It replaces a now deprecated extension and is very valuable to me. I am having an issue with 3.72 that others have reported. Namely, when I delete a search engine the list of search engines disappears. A refresh brings it back, but this adds a lot of time to the removal process.
