It does what it says, lets me search through custom search engines thru the context menu, but It is unnecessarily complicated, and the reliance on a 3rd party for adding search engines is a turn-off. Else, you have to add all the fields manually, which might not be the best way for a common Joe. There are a few other extensions that let you add search engines through bookmark keywords, which seems like a very easy way and doesn't involve manual configurations or 3rd parties. I wish this was an option here.

For now, I'm using this one because its the only one I have found that supports POST, but I will be looking for alts.

I'm thrilled to see such a simple-yet-powerful context search extension for FF 57+ and similar to the old, unsupported Context Search plugin we all loved. Big props to dev for making this happen and thank you thank you! ;)

The Quick Menu doesn't work, how do I get it to appear? The setting is enabled.
*answer to developer*By quick-menu I mean the little square with icons of all the search engines I added, and not the bottom row of the regular right-click menu. I was on facebook, and some other sites. I tried double-clicking the word and also selecting it by dragging. Is there another way to activate it?

Super impressive. This is not just another context menu search extension, it's more than that! Unexpected but much appreciated features and customization. Seems to have good support and active development.

when I try to install the app, my antivirus puts it in quarantine. not happy

Thanks! It's perfect. It is also a excelent alternative to "Add to search bar".

Отличное расширение.
Особенно хорошо сделали опцию для создания поисковой системы через ПКМ по нажатию на поле поиска-сайта, с автоматическим подхватыванием адреса-поиска.
p.s Quick Menu dont working in Firefox 59.

Sorry. Everything is working. It was necessary to simply reinstall.

Very Nice! Thanks

»Add Custom Search« is super!

:-)

Very good..!

Powerful and nice design, but it does not allow to add new custom search engines... (as it is impossible to add in Firefox too...). So quite useless. I prefer the extension "Context Search WebExtension" which allows custom search engines.

Edit: Thanks for your quick answer.
Actually I hide the Firefox' search text box in order to save space for all my addon icons + my bookmarks in toolbar... (It would be so great to have an additional bookmark toolbar... before I used Classic Theme Restorer which allowed it). So I can't see the green "magnifier" when Firefox detects a search engine.
On top of that, the majority of the websites I use don't have an OpenSearch compliant search box. For instance www.discogs.com.
So I find the Firefox OpenSearch standard search engine too restrictive. This is not a critic against your addon, but this is a critic to Firefox.

This was the add on I was waiting for.

Install a tiny open-source app to keep your search engine list updated autom.
It is much better if you insert this open source plugin into itself. And if possible, when I install the plugin, pop up window is set

Well done
great work.
Thanks

reply thanks
I think good add-on because use in textbox

I'm sorry, my English is not good

"Selection Context Search"(add-on) has function
https://addons.mozilla.org/ja/firefox/addon/selection-context-search/
close the popup window when scrolling
close the popup window after ? seconds

I hope
these two config to add

A few weeks ago, it almost could replace my old extension, that i used before quantum - now its even better.
GREAT, FAST WORK!
Thank you :-)

Works great and fast, great communication with developer on GitHub.

Nice replacement for the old Context Search add-on which I started to miss bitterly right after Firefox 57 came out. Something like this should REALLY be standard in Firefox.

That said, getting the add-on to work in "Automatic" mode on GNU/Linux (Ubuntu, in my case) was a bit of a hassle. The instructions on the GitHub site could be more helpful here. They put too much focus on the location of ContextSearch.json (no, DON'T put that file or anything else under /usr/lib/ or /usr/lib64/, these are to be maintained by your package manager alone) and leave more important points unmentioned.

To make a long story short, I had to do the following:

(1) Put ContextSearch.json and ContextSearch.py from the git repository into ~/.mozilla/native-messaging-hosts/.

(2) Make ContextSearch.py executable (chmod u+x) AND convert it from CR/LF (Windows) to LF (Unix) line endings so that python can actually run the script. (I also changed the shebang to #!/usr/bin/env python).

(3) Change the path value in ContextSearch.json to the actual location of ContextSearch.py (why doesn't it just default to ContextSearch.json and ContextSearch.py being in the same directory?).

(4) Enter the path of my search.json.mozlz4 file in the add-on's preferences.

And hey not-quite-presto, everything works! Well, apart from a few details, like search engines using POST rather then GET requests not working but showing up in the context menu. All in all, a promising extension with a few rough edges.

Perfect extension for replacing Firefox's built in context menu search which is fairly limited.

At this moment this extension is the best contextual menu searcher. It made me update to FF 57. Thank you very much.

Very handy Context Search is Back in different Shape!!!

Works just like the old contextsearch plug-in on the old firefox version. Added functionality of the quick buttons is a nice touch and being able to resize them is a good option on screens with a very high pixel density.
