abandoned and no longer works :(

Incredibly useful light addon, but it just stopped working on FF129. Is there any support site?

A great and very helpful add-on, but it doesn't work since FF version 128.

Still 5⭐,but a question as well: Why it stays on only few seconds and when cursor is moved the pop-up shuts off?

Nice and useful addon. Unfortunately, Google reverse image search doesn't work.

手軽に検索出来ます
しかも何で調べるのか指定も設定(検索欄を右クリック)も可能。凄い
カカクコムは文字化けするようなので

This was/is one of the better search addons.

So you might ask why the low review:

1). It was delisted from Google for Privacy Violations. Thus clearly there are Privacy concerns.
2). The code is obfuscated.

Нет возможно выборочного поиска на нескольких сайтах одновременно. Нет папок и подпапок.
Фигня! 😒

The Favicon of each search engine is not "cached" to disk drive, they must to be re-downloaded after every firefox restart, it will be better if these favicons been cached.

Does not work on "faceitfinder"
We need the last word in the link for work. ~$*$~

Все работает, кроме автокопирования в буфер и никакие настройки не слетают. Упоминаемое ниже расширение даже рядом не валялось с этим аддоном, так как добавляет свой пункт только для выделенного текста, а в этом раздельные подменю для разных контекстов - картинка, фрейм, вкладка, страница, ссылка. Например можно передать адрес картинки для поиска по изображению или адрес сайта/ссылки для для открытия в Google Trnslate, или получения информации о сайте/домене и т.п. Аддон обновлялся два года назад, но даже сейчас он способен добавлять свои пункты в контекстное меню вкладок, в том числе и вкладок TST.

Previously this addon worked fine, now though not a single option provided by default works, nor do those I've created myself. Do not waste time downloading.

I have used it for years. And I was happy with it, I used it extensively all day long. But when it was last updated two years ago, this previously excellent extension suddenly lost the ability to keep personal settings... You have to reload them in memory from your backup every new Firefox session! An extremely annoying and time-consuming process. As a result, the extension loses most of its interest, and the developer seems to have completely abandoned it. About six months ago I switched to another extension, Swift Selection Search, which does exactly the same job (minus the custom sub-menus) but works perfectly and with the same possibility to save personal settings... but which doesn't require to reload them manually at each Firefox session. A dream! This Selection Context Search extension lost all its interest when it was updated two years ago. Better to switch to Swift Selection Search.
