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!

New version is shit, but reverted to 2.3.0.4 and disabled update, works well again.
