Took a few minutes to figure out but seems to work well.

非常好用！五星好评！！！

It is a great extension for reverse image search. It's customizable and quick.

good

Very usefull extension for getting sauce :^))

Hi, it's a a great extension that I've loved for long but does the new version not work in some old version Firefox? After the latest update I found the image search option no longer appear in the right click menu. Since I'm using Firefox 43.0.1, a fairly old version, I guess there might be some compatibility issues?
I see in the release notes it's been said 'go to extension's options page to change anything'. However, the 'Option' button for this extension in Add-ons Manager disappeared as well so I couldn't make any change.

画像検索の選択肢が多くなるので、重宝してます。

Great extension, been using it for years in multiple browsers. For what I need, it works flawlessly. One question though: is it possible to remove or "uncheck" the 'Use Alternate' option from the context menu? I only use two search engines and added 'Search All' just in case.

P.S. If you're planning to use the 'Use Alternate' option to offer a way to search for local images, then I retract my question, as I want that too, when you'll find a working solution :D

RESPONSE TO THE DEVELOPER:

Thank you. Don't worry about the timeline - I understand the difficulty of adapting your sofware to these constant changes in browsers, given the fact that I am also in a process of developping an extension for Chrome...;)

"hold Shift to use alternative option" doesn't work.

Somebody listens! The ability to fine tune a context add-on. This on lets you open in a new tab OR window, choose which search engines or another program to search in as well as save your preferences. Good Show!
