Amazing! It should serve as standard of a properly written add-on for other developers. Small feature suggestion: add an option for appending selection to clipboard. This could be a real click-saver and a replacement for addons like "AddMoreTextToClipboard" or "Text MultiCopy". It could have the following options:
1. Append to clipboard (no separator)
2. Append to clipboard (add line break)
3. Append to clipboard (add double line break)
4. Clear clipboard.

hello and thanks for this good add on. is there any way that i can sync search bar of firefox with the sss context menu. I imported the search.json.mozlz4 but I want when change the order of engines and add some new ones, the searchbar synces with that. what should i do? is it possible at all? i get an export file but I didnt know what should i do...

I have tested several similar addon, and this has everything I needed. Great addon.

Excellent extension, just two very, very minor suggestions. 1) Could you add a maximum character limit option to the auto-popup. You already have a minimum limit, and personally, I'd rather not have the thing pop up when I'm copying a whole paragraph. 2) I couldn't find this extension when looking for "context search" in the addon library, so maybe improve your SEO in the

Best one I've found.

Just Sooooo Goooddd...

must have add-on

I am loving this extension! Just wondering if you could add a user page or something where users can submit more examples (If something like this already exists, please let me know!)? A couple of things I'm looking for but haven't figured out just yet are how to have the selected text's hyperlinked url open as cached link [basically launch url as a google webcache search] or similarly open link as viewsource. Hope that somehow makes sense.
Here's some dumb ones I use regularly, lol, if anyone cares. :D

In any event, the app is awesome. Highly recommend!

非常好用，自定義常用搜尋引擎後，省掉不少時間

Last thing you need to ad: the possibility to disable the plug-in from a personal list of websites!
